Quarterbacks1. Sean Mannion, Oregon State: Mannion had a second day at the Senior Bowl. He consistently threw with accuracy, throwing quite a few nice deep balls and dropping passes over linebackers and under safeties in coverage in seven-on-seven and team drills. Mannion doesn’t have the arm strength like Bryce Petty but it’s plenty good enough. He showed good field vision and made some good reads.
2. Bryce Petty, Baylor: Petty can really spin the ball and the kid from Baylor has arm talent. He struggled with consistency and missed on some easier throws on the day. There were times, though, when he threw to spots effectively. He was more effective working the sideline routes and crossing patterns.
Running backs1. Tyler Varga (FB), Yale: A new leader emerged on day two of Senior Bowl practice from a nice group of running backs on the North roster, and he is a name only the most staunch of college football fans might recognize. Varga is one of two Ivy League players in the game and he had a great Day 2. The most impressive thing about Varga today was his physical play and running style. He showed well in pass-protection drills when working one on one against blitzing linebackers and also displayed enough speed to bounce outside for a nice gain during the team portion.
2. Jeremy Langford, Michigan State: Langford turned in another good showing on Wednesday. He did nothing to hurt himself and was passed for the top spot simply because of the improved showing of Varga. Langford was most impressive during the team portion when he showed he can catch the football out of the backfield and make a play downfield.
3. David Cobb, Minnesota: Cobb showed his true abilities on Wednesday, running with a much more physical style. He does not have great top-end speed but looks very decisive, and when he made cuts he did not dance, he lowered the shoulder and ran hard to contact.
4. Ameer Abdullah, Nebraska: Abdullah fell today because he struggled in pass protection against both linebackers and defensive ends. He showed his offensive abilities during the team drills, but because of his small frame and light build he is susceptible to bull rushes when left one-on-one against pass rushers who have a running start.
Wide receivers1. Devin Smith, Ohio State: Smith came to this event hoping to dispel the notion that he’s a one-trick pony and deep threat only. He shows excellent hand-eye coordination on short routes coming out of his breaks with the ball and defender all over him. Smith is not only fast but scrappy and aggressive when he needs to be as the route develops or battling for the ball. He was effective running sideline routes and patterns over the middle and caught the ball very well on Wednesday.
2. Jamison Crowder, Duke: This future slot wide receiver had another solid day. He’s so quick off the line and has excellent speed, Crowder shows soft hands and catches the ball consistently well away from his body. He doesn’t fight it and lets ball get to his body. Crowder is a deceptive route runner and showed he can run all the patterns, whether deep, short or intermediary. He had the catch of the day, which was a one-handed sideline grab.
3. Tony Lippett, Michigan State: This Spartan is a long strider who showed he can run away from defensive backs after the catch. He’s long and physical and also showed he’s not afraid to put a hat on a defender to help block for his teammates. Lippett catches the ball well and away from his body.
4. Justin Hardy, East Carolina: A big-play wide receiver, what jumped out with his skill set is his ability to separate from the defender, especially with the ball in the air. He just has another gear. He did some nice things on the day but also dropped a pass or two and needs a more consistent day Thursday.
5. Ty Montgomery, Stanford: Montgomery looks the part and at times has been very impressive, but he’s also had his share of drops. He has size, length and good speed. Montgomery showed the ability a few times today to make something happen after the catch. He’s fluid, smooth and can be physical. He just needs to put a complete practice together. You can just see that this kid has talent.
Tight ends1. Ben Koyack, Notre Dame: He made a nice catch down the middle of the field early on in Wednesday’s practice and has good body control and gets decent separation. He is still showing as the best tight end on his team.
2. Nick Boyle, Delaware: Boyle missed a block early, but rebounded with an excellent reception near the sideline as he stretched high to snag the pass, then had the presence of mind to get both feet down just in bounds. He continues to impress with receiving skills.
3. Casey Pierce, Kent State: He’s caught his share of short-range passes on sideline outs and crosses. He has shown glimpses of speed, but he can probably do a lot more on deep routes down the seam. Don’t be surprised if he asserts himself more as the weekend nears.
1. T.J. Clemmings, Pittsburgh: Clemmings is a powerful specimen; holds up well at the point of attack. A great anchor and sure-fire pro prospect.
2. Rob Haverstein, Wisconsin: Haverstein has a lot of fight and a streak of nasty in him. He showed well in his one-on-one drills.
3. Donovan Smith, Penn State: Many believe that Smith needs a lot of work to iron out his kinks as a pro prospect, but he held his own on Wednesday, both in one-on-ones and in group drills.
1. Laken Tomlinson, Duke: Tomlinson is a ferocious dual-threat prospect. Can play at guard and spent some time at center on Day 2. He’s the best interior lineman for the North squad.
2. Ali Marpet, Hobart: Marpet played hard on Day 2 and held up at the point of attack. You’ve got to love his blue-collar spirit.
3. Robert Myers, Tennessee State: Myers played tough, but didn’t do anything to set himself apart on Wednesday.
1. Max Garcia, Florida: He continues to solidify his status as the best center on the North squad, but watch out for Tomlinson, who lined up with the ball a few times.
2. Chris Jasperse, Marshall: He’s working hard and firmly believes he can improve his draft status with a great performance this week.
Defensive Tackles1. Danny Shelton, Washington: Shelton had another strong day in practice, stonewalling his assignments in double-team drills.
2. Marcus Hardison, Arizona State: Hardison is still breathing down Shelton’s neck. When they lined up together in 11-on-11 drills, they were a sight to behold.
3. Carl Davis, Iowa: Davis has terrific size and is able to leverage it to put offensive linemen off-balance. He had an impressive second day.
4. Louis Trinca-Pasat, Iowa: Davis’ trench-man at Iowa wasn’t dominant but plays with a lot of heart and has a motor.
Defensive Ends1. Nate Orchard, Utah: Orchard played mostly with the linebacker group on Day 2 but was just as explosive standing up. In 11-on-11s, he showed good run-blocking responsibility, crashing down the line to seal off the runner’s cutback lane.
2. Za’Darius Smith, Kentucky: Smith is a specimen and plays with a chip on his shoulder. His bull-rush is powerful. He had a good second day of practice.
3. Henry Anderson, Stanford: After not making the notebook on first day, Anderson made several good plays on Wednesday. He impressed holding up at the point of attack and setting the edge.
4. Deion Barnes, Penn State: Barnes had a solid day, but there wasn’t much to write home about. He does have some pass-rush moves in his tool box that NFL teams covet but needs to showcase them more consistently while at the Senior Bowl.
Linebackers1. Hayes Pullard, USC: Pullard stepped up in a big way on Day 2, showing his speed and a much more physical game with the pads on and more contact allowed. He was particularly impressive in one-on-one work against running backs in blitz pick-up situations by running over Ameer Abdullah on one play.
2. Jeff Luc, Cincinnati: Luc stays in the top five for the second day, and was just as productive and disruptive as on Tuesday. He is undersized in height but is perhaps the most physical linebacker in this class. He is improving his stock with every rep.
3. Mike Hull, Penn State: Hull’s performance did not slip from Day 1 to Day 2; it was the improved performance of Pullard and Luc that dropped Hull from yesterday’s top spot.
4. Jordan Hicks, Texas: The Longhorns product showed a fierce bull rush Wednesday, especially in the position portion of practice when he showed consistency throughout the practice in taking on and defeating one-on-one blocking from tight ends or running backs.
5. Zach Hodges, Harvard: It’s hard to say that a mistake helped Hodges make the top five on Day 2, but that is exactly the case here. Early in the practice Hodges made a mistake and was immediately called over by his position coach. Hodges took the mistake hard and was visibly upset with himself. However, he bounced back and had a solid effort after that. It looks like the young man cares and can take coaching, two things that bode well for him going forward.
Cornerbacks1. Quinten Rollins, Miami-Ohio: This should tell you what you want to see in a cornerback: He covered Devin Smith, the best receiver at the Senior Bowl, well. The former point guard continues to show great potential after only season of college football and can keep up with the big-school speedsters.
2. Doran Grant, Ohio State: After a decent day on Tuesday, he continued to show good downfield coverage on the second day of practice.
3. Quandre Diggs, Texas: When big-bodied receiver Tony Lippett is saying Diggs is physical, you know it’s true. He was aggressive in taking on receivers and showed a knack for playing the slot receiver and working in traffic.
4. Josh Shaw, USC: For a big cornerback (6-1, 200), he wasn’t as physical on Wednesday, but he showed he can shadow a receiver nicely and run stride-for-stride. The only downfall was that he got turned around a couple times.
5. Steven Nelson, Oregon State: He struggled to get off blocks to help in run support, but he shows a good feel for zone coverage.
Safeties1. Kurtis Drummond, Michigan State: Had a relatively quiet practice, playing a lot of solo safety in Cover-1 looks. Seemed a bit more hesitant this day when it came to reacting to plays and jumping into the defensive box. But he looks at ease when alone on back line of defense.
2. Ibraheim Campbell, Northwestern: No safety on either squad handles the shed-blocker drill like Campbell. His shoulder pads pop on contact, he quickly throws aside the blocker and wraps up the ball carrier. It’s one of the few times he can hit. It will be interesting to see what he does on game day.
3. Damarious Randall, Arizona State: He’s conscious of the need to gain weight, saying after practice he’s up to 194 and will be at about 197 by the NFL Scouting Combine. He’s displayed decent cover skills for a safety. And it’s to his credit that he knows he needs to add size to measure up in the NFL.
4. Adrian Amos, Penn State: He didn’t get burned like the first practice, but also didn’t make any noteworthy plays, either. That translates to a slow start. But there’s still plenty of time for him to show why some draftniks have him rated rather high at his position.
