NFL Draft: Scouting The Offensive Tackles

The Niners will be looking for an offensive tackle in the draft, particularly if they don't match the offer sheet signed by Kyle Kosier.

Here's a capsule synopsis of the top prospects available in the draft this weekend

Alex Barron School: Florida State
Ht: 6-7.5 Wt: 320 40: 4.91 Year: 5Sr

Bio: Full-time starter the past two seasons and named to both the All-American and All- Conference teams. Played five of fourteen games with the first unit as a sophomore in ‘02.

Positives: Outstanding blind-side protector with excellent size and upside potential. Quickly sets in pass protection, immediately gets his hands into defenders and extends to keep them from the action. Strong in his upper body, displays good hand punch and bends his knees, staying low to the ground throughout the play. Easily controls opponents once engaged in a block, knocking them back off the ball. Effective position blocker who walls opponents from the action. Displays good movement skills, can slide in space and fluid shuffling out to protect the edge. Blocks down or engulfs opponents. Keeps his feet moving and anchors in pass defense. Easily adjusts picking up stunts or blitzes.

Negatives: Tries to outguess defenders and gets beat. Lazy with his hands. Must make better use of blocking angles and learn to play with balance. Does not play with a nasty attitude and by no means a dominant drive blocker who opens big holes for the running game. Work ethic has been questioned.

Analysis: Possessing a tremendous amount of natural skill, Barron possesses all the physical traits necessary to be an early pick and a productive left tackle in the NFL. Before any of that will happen he must pick up the intensity and tempo in all areas or will never reach the level of achievement scouts think he is capable of.
Khalif Barnes School: Washington
Ht: 6-5.5 Wt: 305 40: 5.00 Year: 5Sr

Bio: Four year starter at both left and weakside tackle. Previous All-Conference selection who missed half the season last year with a broken wrist. Considered the best player on the Washington football team.

Positives: Big, athletic lineman soaring up draft boards. Sets with a wide base, works to bend his knees and keeps his feet moving throughout the action. Quick off the snap and a solid position blocker who seals running lanes. Patient, makes good use of blocking angles and powerful at the point. Jolts defenders with hand punch and controls them once engaged in a block. Nasty, engulfs opponents or buries them into the ground. Had a sensational week of Senior Bowl practice when he devastated the opposition.

Negatives: Not a nimble lineman, has difficulty adjusting and beaten by inside moves. Cannot redirect to linebackers on the second level. Does not play with great balance or show top blocking range.

Analysis: An offensive tackle prospect with excellent measurables and a lineman who tests well, Barnes has been on a straight shot North since January. Needs to polish his game and improve his footwork in space yet possesses the underlying natural skills to become a productive starting tackle in the NFL.
Jammal Brown School: Oklahoma
Ht: 6-6 Wt: 316 40: 5.07 Year: 5Sr

Bio: Three-year starter and an All-Conference selection since his sophomore campaign. Named as an All-American the past two seasons. Awarded the Outland Trophy in ‘04, handed to the nation's best interior lineman.

Positives: Big, athletic tackle built for the right side. Quick into blocks, displays good hand punch, and easily rides opponents from their angle of attack. Gets out to the second level and walls linebackers from the action. Powerful, easily controls opponents or turns them from the action. Patient in pass protection, anchors at the point and stays low throughout the action. Mentally alert, works well with teammates, and gets movement from run blocks when focused.

Negatives: Does not consistently attack run blocking assignments. Controls opponents, yet does more steering than actual finishing. Heavy-legged and not effective in motion. Could improve his hand placement.

Analysis: An athletic prospect with terrific upside potential, Brown projects well to the next level. Has first-round potential and could be a productive lineman for a long time to come if he develops a mean streak.
Adam Terry School: Syracuse
Ht: 6-8 Wt: 330 40: 5.44 Year: 5Sr

Bio: Three year starter who's been an All- Conference selection the past two years.

Positives: Durable left tackle with good potential for the next level. Solid athlete who stays square and controls opponents once engaged in a block. Quickly gets his hands up, patient and effectively uses blocking angles. Plays with leverage, jolts opponents with his hands, and is solid as a position blocker. Nasty, yet at the same time an alert blocker who quickly picks up assignments or blitzes thrown by the defense.

Negatives: Does not play with great body control, does a lot of slipping and continually on the field. Has a tall, thin build and stands to improve the strength of his base. Lacks top footwork and overall blocking range.

Analysis: A productive lineman who's continually improved, Terry's combination of growth potential and athleticism bode well for the next level. Not the prettiest yet has consistently gotten the job done, and possesses the tools to be an effective starting tackle for an NFL team after a season of development in the weight room.
David Stewart School: Mississippi State
Ht: 6-6.5 Wt: 314 40: 5.25 Year: 5Sr

Bio: Three-year starter who saw action with the first team as a freshman. Consistently graded out as Mississippi State's top offensive lineman.

Positives: Hard-working blocker coming off a terrific senior campaign. Nasty lineman who works to bury opponents. Stout, anchors at the point and easily turns defenders off the line. Strong, yet at the same time intelligent, and works well with teammates.

Bends his knees blocking with leverage, powerful in the upper body and displays excellent arm extension with the ability to control defenders once engaged at the point. Surprising skill pulling across the line of scrimmage and blocking in motion. Jolts defenders and explosive at the point.

Negatives: Not light on his feet, lacks adjustment and exploited by nimble opponents. Cannot redirect to defenders on the second level. Marginal blocking range.

Analysis: Looking like a different player as a senior, Stewart took his game to another level and is now a prime strong-side tackle prospect for the next level. Possesses the nasty demeanor coaches want, yet at the same time, plays with the intelligence and self-control needed to be successful in the NFL. Moved himself into the draft's first day and could quickly find himself as a starter at the next level.
Wesley Britt School: Alabama
Ht: 6-8 Wt: 314 40: 5.31 Year: 5Sr

Bio: Moved into the starting rotation as a red-shirt freshman and awarded All-Conference honors last year as a senior.

Positives: Big, tough lineman with an excellent feel for blocking. Quickly picks up assignments, patient in pass protection, and works hard until the whistle blows. Anchors at the point, displays excellent awareness and always looking for someone to hit. Effectively uses body positioning and blocking angles to seal the edge and protect the passer. Outstanding hand technique and extends to keep defenders away. Blocks with knee bend and works to get leverage on opponents. Immediately sets up in pass protection, jolts opponents run blocking and quick in all aspects. Tough and plays while injured.

Negatives: Not overly agile and at times looks downright unathletic. Lacks adjustment, not comfortable in space, nor is he a dominant drive blocker. Suffered bone injuries in both legs as a junior, then again in the Senior Bowl last January.

Analysis: Working hard for sixty minutes and using all his assets to a maximum, Britt has been a productive left tackle on the college level the past four-years. And while some debate his ability to stay at that spot in the NFL, few question his potential as a starting blocker down the road on the strong side. Solid selection in the middle of round two.
Nick Kaczur School: Toledo
Ht: 6-4.5 Wt: 319 40: 5.32 Year: 4Sr

Bio: Celebrated lineman who's started every game during his Toledo career, winning All- Conference honors since his freshman season.

Positives: Nice-sized lineman who projects to the strong side. Nasty blocker who quickly sets in pass protection, displays patience and keeps his feet moving throughout the action. Extends his hands into opponents and easily controls defenders at the point of attack, anchoring at the line and not giving up an inch of ground. Dominant, and moves defenders off the ball. Blocks with leverage, gets underneath opponents and an immovable force. Outstanding hand technique and overall body strength.

Negatives: Bends at the waist, lacks adjustment and looks stiff. Lacks top footwork sliding off the edge and cannot redirect the linebackers at the next level.

Analysis: A competitive blocker who plays with a mean streak, Kaczur offers potential at several spots up front. Better off at tackle where he has room to work and should be solid on the right side, though he could also be moved to the blind side in a pinch. Solid first-day consideration.
Ray Willis School: Florida State
Ht: 6-5.5 Wt: 327 40: 5.41 Year: 5Sr

Engulfs opponents or blocks down to remove them from the action.

Negatives: Big lumbering blocker who lacks adjustment and overall quickness. Struggles sliding his feet, lacks blocking range and overextends at times.

Analysis: A high-effort prospect with good work ethic, Willis has the tools to develop into a starting right tackle in the NFL. Most effective in a zone-blocking scheme or a system that limits his area responsibilities.
Michael Roos School: Eastern Washington
Ht: 6-6.5 Wt: 320 40: 5.33 Year: 5Sr

Bio: Three-year starter awarded varying degrees of All-Conference honors since his sophomore campaign.

Analysis: A solid technician who's improved every year, Roos possesses good upside for the next level. Mainly used at right tackle in two postseason games by NFL scouts thought he seems to have enough foot quickness and lateral slide ability to protect the blind side at the next level. Solid development prospect whose abilities make him worth consideration in the late part of the draft's first day.
Calvin Armstrong School: Washington State
Ht: 6-7 Wt: 325 40: 5.51 Year: 5Sr

Bio: Moved into the starting lineup as a redshirt freshman and has won varying degrees of All-Conference honors the past three years.

Stays square, keeps his feet moving and displays solid blocking strength when he applies himself. Strong upper body and rides defenders from their angle of attack. Works well with teammates.

Negatives: Lacks top agility, blocking range and not a natural knee bender. Bends at the waist and overextends. Not physical run blocking, rarely moves opponents off the ball or finishes blocks.
