— Mike Adams, Ohio State (6-8, 320): Adams was a second-team all-Big Ten choice as a senior, even while playing only seven games, after picking up first-team honors as a junior. He was suspended for the first five games of the 2011 season because of the tattoo scandal that enveloped the program. He returned to face Nebraska and dominated another potential first-round pick, Jared Crick. He missed time as a freshman with a shoulder injury and as a sophomore with a knee injury.
— Jeff Allen, Illinois (6-5, 315): King was a four-year starter, opening his career by making freshman all-American teams at right tackle before spending his final three years at left tackle. He was second-team all-conference his final two seasons and an academic all-Big Ten choice, as well. In all, he started the final 47 games of his career. King wasn't highly recruited. Attending an Illinois football camp, he asked coach Ron Zook what it would take to be given a scholarship. Zook told the 335-pounder to lose weight, got down to 290 for his senior season.
— Justin Anderson, Georgia (6-5, 342): Anderson started seven games at right tackle as a freshman and five at right guard before being benched as a sophomore. As a junior, he was moved to defensive line and played in one game at nose tackle before undergoing season-ending surgery for turf toe. Back to the offensive line for his senior season, Anderson started all 14 games at right tackle. "Bean" has always been a big kid, as his mom told Bulldawg Illustrated: "All of my kids played sports and one thing I always remember is that they were outside racing all the time. Justin was always so big that when he took off running, he would leave a big hole in the ground where he took off."

— Tony Bergstrom, Utah (6-6, 315): Bergstrom started one game at left tackle as a freshman before starting the final three seasons at right tackle. The team's leader, he was a first-team all-Pac-12 pick as a senior. He'll have turned 26 when training camp begins after spending two years on a LDS church mission. Bergstrom was 6-foot-5 in eighth grade and was just 240 as a senior in high school. His cousin is Major League Baseball player Ryan Roberts, and his wife, Jessica, is the sister of Baltimore Ravens defender Paul Kruger.
— James Brown, Troy (6-4, 312): After a year in junior college, Brown was the first-team all-Sun Belt Conference left tackle all three years at Troy. Before his senior season, he dropped about 20 pounds, and he was rewarded with a senior season in which he was penalized twice and piled up 110 knockdown blocks, according to the coaches. In 2005, he was a Mississippi weightlifting champion.
— Tom Compton, South Dakota (6-6, 314): Compton was a starter all four seasons — the first two at right tackle and the final two at left tackle. He was a first-team All-American and the Great West Conference lineman of the year. According to coach Ed Meierkort, he allowed only one sack in his career — to Montana State's Dane Fletcher, who plays for the Patriots.
— Paul Cornick, North Dakota State (6-5, 309): After starting 12 games at right guard as a junior, Cornick bounced outside for his senior campaign. He was an All-American who graded out at 96.5 percent for the season with one sack, no additional hurries and 102 knockdown blocks to help NDSU win the FCS national championship. Rams safety Craig Dahl is the only other North Dakota State player to ever be picked for the Combine.
— John Cullen, Utah: Cullen (6-5, 300): Cullen spent two years at Fullerton College and was the top-rated junior-college lineman before arriving at Utah. He started both seasons at left tackle or the Utes, earning second-team all-conference honors as a senior. Cullen, who also played rugby in high school, was called "dirty" by a member of Pitt's defense; he prefers to call it playing through the whistle. Cullen's middle name is Wayne — yes, he was named after the legendary actor.
— Andrew Datko, Florida State (6-6, 321): It was a miserable senior season for Datko, who started at left tackle in each of his first three seasons in Tallahassee. A shoulder injury that hindered him as a junior cut his season short after just four games in 2011. In 2010, he allowed one sack in 11 games. He could have applied for a medical redshirt so he could play for FSU in 2012, but with degree in hand, he elected to turn pro.
— Taylor Dever, Notre Dame (6-5, 301): Dever started his final two seasons at right tackle. One of the better high school offensive tackles, the former Nevada Union star (Nevada Valley, Calif.) had plenty of suitors but sent his film to Notre Dame's scouts. He earned his degree in marketing and was enrolled in graduate studies.
— Cordy Glenn, Georgia (6-5, 348): Glenn, a third-team All-American as a senior, and Clint Boling (Bengals) are tied for most starts by a Georgia offensive lineman with 50. As a sophomore, he started games at both guard slots and left tackle. After playing left guard as a junior, he switched to left tackle for his senior year. In summer 2010, Glenn was timed at 4.82 in the 40. As a kid, Glenn focused on basketball — his father played for Louisiana-Lafayette — and didn't play football until the ninth grade.
— A.J. Greene, Auburn (6-5, 295): Greene, who was recruited to play defensive end, started just three games in his first three seasons — all in 2010, when his season ended with a broken ankle. As a senior, he didn't emerge as a starter at the end of fall camp but quickly was plugged into the lineup at right tackle. One of Greene's passions is music. He and former Auburn basketball player Francisco Aihe partnered to create "Orange Navy Anthem."
— Lamar Holmes, Southern Mississippi (6-6, 333): Holmes was a first-team all-conference left tackle for the Conference USA champions. Holmes was a basketball player at Huss High School in Gastonia, N.C., until giving football a try as a junior in high school. He spent two years at Itawamba Community College in Fulton, Miss., before going to Southern Miss.
— Marcel Jones, Nebraska (6-7, 320): Injuries have sabotaged Jones' career. Jones started 11 games at right tackle in 2009 before an ankle injury ended his season. He missed most of 2010 with a back injury. He was held out of the starting lineup for the first four games of 2011 with a shin injury. In all, he started 21 games. Jones earned his degree in construction management in December and was active in the Lincoln community.
— Matt Kalil, USC (6-7, 295): Kalil entered the draft following a junior season in which he was named to most All-American teams and won the Morris Trophy as the Pac-12's top lineman. He's expected to be a top-five pick. Kalil didn't allow a sack in 2011 and used his height to block four kicks. Football is in his DNA. His father, Frank, was a center who was drafted by the Bills and played in the USFL for two seasons. His brother, Ryan, played for USC's national championship teams in 2003 and 2004 and plays for the Panthers.
— Senio Kelemete, Washington (6-4, 301): After starting four games on the defensive line as a freshman, Kelemete was a three-year starter on the offensive line — at right guard as a sophomore and left tackle as a junior and senior. Kelemete was a second-team Pac-12 selection in 2011. He was just the third offensive tackle in school history to be a two-year captain.
— Ronald Leary, Memphis: (6-3, 325): Leary, a starting left tackle as a sophomore and junior, opened the first six games of his senior season at left tackle before being forced inside to right guard because of injuries. He started all 36 games over his final three seasons, earning second-team honors in Conference USA and being named one of the team's offensive MVPs as a senior. Of his six siblings, all are sisters, and he admits that he left them put in him a dress and makeup when he was young.
— Jonathan Martin, Stanford (6-6, 304): Martin started all three seasons at left tackle before declaring for the draft, where he's a potential top-10 selection. Protecting Andrew Luck's blind side, Martin was a second-team All-American in 2011. "Moose" was recruited by Harvard, where he would have been the school's first fourth-generation African-American student. Harvard might gets its man, anyway, if he winds up in law school after his playing career is over.
— Bobby Massie, Mississippi (6-6, 315): Massie elected to bypass his senior season to enter the draft. He played in every game the last three seasons, starting the last 29 at right tackle. Massie blocked for 14 individual 100-yard rushing performances, including a pair of 200-yard performances. To prepare for the draft, he worked out at the O-line academy started by Cleveland native and former Saints standout LeCharles Bentley.
— Matt McCants, Alabama-Birmingham (6-7, 295): McCants started his final three seasons at left tackle, earning first-team honors in Conference USA as a junior and senior. McCants broke into the starting lineup as a freshman but sat out 2008 for academic reasons. McCants played football as a senior at Williamson High School in Mobile, Ala. Before that, he played the tuba because his mom didn't want to see her "little" boy get hurt. Mom gave in after McCants earned all A's on his report card.
— Brandon Mosley, Auburn (6-6, 310): Mosley started 13 games as a senior, including 12 at right tackle, to earn second-team honors in the SEC. He also started 11 games as a junior as the Tigers won the national title behind a rushing attack that churned out a school-record six consecutive 300-yard rushing games. Before playing at Auburn, Mosley played tight end and defensive end for Coffeyville (Kan.) Community College. He arrived at Auburn as a tight end but quickly bulked up to play on the line.

— Kelechi Osemele, Iowa State (6-6, 347): Osemele earned first-team accolades in the Big 12 as a senior, wrapping up a career in which he made 43 consecutive starts. His final two seasons were spent at tackle after playing guard to start his career. Osemele's parents, Imelda (a pastor) and Paul, had three girls; they wanted a son and thanked God when Kelechi was born. In fact, that's what his name means when translated from its Igbo origin: Thank God.
— Nate Potter, Boise State (6-6, 295): Potter entrenched himself as the starting left tackle during his sophomore season, earning first-team honors in the WAC all three seasons and second-team All-American honors as a senior. Boise State has become something of a left tackle factory, with its player earning first-team accolades for the past eight seasons, starting with Daryn Colledge in 2004 and 2005, and Ryan Clady in 2006 and 2007. Potter worked out with Colledge during the past few offseasons. Potter earned his business degree in May and is working toward his graduate degree.
— Riley Reiff, Iowa (6-6, 300): Reiff started games at left tackle, right tackle and left guard as a freshman — earning freshman All-American recognition — before replaying Bryan Bulaga as the left tackle in 2010. Reiff roomed with Bulaga and studied film together. Reiff came to Iowa as a defensive end after being the South Dakota Gatorade Player of the Year but moved to the offensive line shortly after arriving at Iowa City. At Parkston High School, he compiled a 121-1 record and won three state wrestling titles.

— Zebrie Sanders, Florida State (6-6, 307): Sanders was a four-year starter, mostly at right tackle his first three seasons and mostly at left tackle as a senior to replace the injured Datko. As a senior, he was named first-team all-ACC and was runner-up for the Jacobs Blocking Award, which goes to the conference's top lineman. Sanders was an Eagle Scout and played the viola in high school — though not by choice. "My mom made me," Sanders told the Palm Beach Post. "I tried to quit first year of high school. She said I couldn't quit until I got out. The day I graduated was the day I threw it in the trash can. Playing an instrument and being good at it is a lot of work."
— Mitchell Schwartz, California (6-6, 318): Schwartz started all 51 games during his Cal career at either left tackle (35) or right tackle (16). He earned first-team all-Pac-12 and Pac-12 all-Academic as a senior left tackle — one of just three players in the conference to pull off the athletic-academic double. He was named Cal's outstanding lineman his final three seasons, and earned second-team all-Pac 10 honors as a junior and an honorable mention as a sophomore. His brother, Geoff, was an offensive tackle for Oregon and just completed his three season with the Carolina Panthers.
— Amini Silatolu, Midwestern State (6-3, 320): The left tackle was an All-American in junior college and as a junior and senior at Division II Midwestern State. As a senior, he finished second for the Gene Upshaw Award, which goes to Division II's top lineman. He's considered Division II's top prospect, according to d2football.com, though he'll probably move inside to guard in the NFL. The school's first player picked for the Senior Bowl, Silatolu injured a hamstring at practice and didn't play in the game.
— Donald Stephenson, Oklahoma (6-6, 307): Stephenson was academically ineligible in 2009 but emerged as a two-year starter at left tackle, earning an honorable mention on the all-Big 12 team as a senior. There are some character flaws teams will want to check out.
— Dustin Waldron, Portland State (6-6, 280): Waldron was the Vikings' top blocker in his four seasons. He was second-team all-Big Sky as a senior, even while missing four games with injuries. At Marist High School in Pleasant Hill, Ore., Waldron was part of state championship teams in football, basketball and track, and he was all-state in football and basketball.
— Brandon Washington, Miami (6-4, 320): Washington was a three-year starter, including at left guard as a freshman and sophomore, with him earning first-team all-ACC honors in 2010. As a junior, Washington opened the season at right tackle before moving to left tackle. He decided to enter the draft a year early, even though his up-and-down play led to coach Al Golden threatening to bench him at midseason.
— Rokevious Watkins, South Carolina (6-4, 340): After two years at separate junior colleges and a redshirt season, Watkins was a two-year starter for the Gamecocks. He played mostly left guard as a junior and started the first five games of his senior season at right tackle before swinging to left tackle because of an injury. He was named second-team all-SEC. While at Creekside High School near Atlanta, he became blood brothers with teammate Eric Berry, the star safety for the Chiefs. He had a rough childhood, admitting to using drugs "and all kind of stuff," but Berry "saved me from that."
— Markus Zusevics, Iowa (6-5, 300): Started the final two seasons at right tackle, earning an honorable mention on the all-Big Ten team as a senior. An impressive athlete at Prospect High School in Arlington Heights, Ill., he was a four-year letterman as an outside hitter in volleyball.
