USC product Matt Kalil, right, may be the first offensive lineman taken in the draft.

The Boston Globe examines the top offensive linemen available in the 2012 NFL draft. Players are listed with position, school, height, weight, and 40-yard dash time. * denotes underclassman:


1. Matt Kalil, OT, USC*/6-6 ½ /305/4.96

Top-notch pass protector is the younger brother of Panthers Pro Bowl center Ryan Kalil, and his father played professionally as well. Very good feet, which serves him well in the run game. Great combine workout, and showed well in drills as well. Will get beat occasionally, but if his focus rounds out, should be a very good pro.

Projected round: 1

2. David DeCastro, OG, Stanford*/6-5/316/5.32


Widely regarded as the best guard prospect since Steven Hutchinson in 2001 (Seahawks). His intensity and competitiveness set him apart in addition to superior hands and terrific feet, as evidenced by the best three-cone time of any lineman at the combine. Can handle defensive tackles, and pull in front of a run. Will start from the first day of camp.

Projected round: 1

3. Cordy Glenn, T/G, Georgia/6-5 ½ /345/5.08

There’s a lot of debate about which position Glenn will play in the pros – guard or tackle. At the Senior Bowl he played left guard and both tackle spots. Some worry about his demeanor – he doesn’t show a natural intensity. Is strong and has long arms. Technique is inconsistent but the tools are there.

Projected round: 1

4. Riley Reiff, OT, Iowa*/6-5 ½ /313

Solid all-around, as most Hawkeye linemen are coming out in the draft. Former state high school champion wrestler has good quickness and knows leverage. Concerns about his arm length remind of former Iowa prospect Bryan Bulaga, who is a very good right tackle for the Packers. Extremely polished pass protector so he could start at left tackle.


Projected round: 1

5. Peter Konz, C, Wisconsin*/6-5/314/5.10

Has very good size to handle the middle of the line against big tackles, but there are questions about his durability as he missed time each of his three seasons (blood clots and ankle problems). Dislocated his ankle late in the season and is still working his way back. Bench press of 18 reps of 225 pounds raised a lot of eyebrows.

Projected round: 1

6. Kevin Zeitler, OG, Wisconsin/6-4/314

Strength (32 reps on bench press) and size standout. Knows how to work in the zone running scheme and gets to the second level well. Solid technique with very good awareness but not a terrific athlete. Had an average Senior Bowl and demonstrated he can fill at center, but he’s likely only a guard.

Projected round: 1-2

7. Mike Adams, OT, Ohio State/6-7 ¼ /323/5.34

Has the prototypical size to be a franchise left tackle, and he flashed that kind of talent at the Senior Bowl. However, the concerns lie in his attitude and desire. Had problems at Ohio State and drew two suspensions (drug possession, selling Big Ten championship ring). Concerns about his maturity linger. Only 19 reps on the bench.

Projected round: 1-2

8. Jonathan Martin, OT, Stanford*/6-5 ½ /312/5.10

Evaluations are all over the map. Some teams think he can be a left tackle, but others see a limited athlete who could even struggle at right tackle. Does not play to his size. Will need to hit the weight room to develop much-needed strength at the next level.

Projected round: 1-2

9. Amini Silatolu, G/T, Midwestern St. (Tex.)/6-3 ½ /311/5.33

Is country strong and has the kind of on-field temperament that reminds a little of Patriots guard Logan Mankins. Very heavy punch, and tested through the roof at the combine. Played last two seasons in two-point stance so will need development in run game. Character will need to be studied. Red flag that he didn’t play in any all-star games.

Projected round: 2-3

10. Bobby Massie, OT, Mississippi*/6-6/316/5.18

Terrific size and arm length that played right tackle in college. Athletically he’s better suited to the left side. Flew under the radar a bit but held his own in the SEC. Focus and mean streak will need to be addressed in scouting process. Good body control and a natural pass blocker.

Projected round: 2-3

Best of the rest

Jeff Allen, T/G, Illinois (6-4, 307, 5.17, 2-3); Kelechi Osemele, OT, Iowa State (6-5 ½, 333, 5.26, 2-3); Zebrie Sanders, OT, Florida State (6-5 ½, 320, 5.33, 2-3); Mitchell Schwartz, OT, Cal (6-5 ½ , 318, 5.38, 3-4); Brandon Brooks, OG, Miami OH (6-4 ½ , 353, 4.98, 3-4); Tony Bergstrom, OG, Utah (6-5 ½ , 313, 5.19, 3-4); Philip Blake, C, Baylor (6-3, 311, 5.18, 3-4); Ben Jones, C, Georgia (6-2 ½ , 303, 5.35, 3-4); Lucas Nix, OG, Pittsburgh (6-5 ¼ , 317, 5.36); Brandon Mosley, OT, Auburn (6-5 ½ , 314, 5.15, 4-5); Matt Reynolds, OT, BYU (6-4 ½, 302, 5.27, 4-5); David Molk, C, Michigan (6-1, 298, 5.25, 4-5); Tom Compton, OT, South Dakota (6-5, 314, 5.06, 4-5).
