NFL Draft scout Josh Buchanan joins our network of expert contributors to weigh in on offensive line Draft hopefuls. Buchanan points out 10 players who could have an immediate impact for any team that op

Josh Buchanan, JB Scouting
1. OT Matt Kalil, USC, 6’6 5/8, 306, 4.96 40
Kalil is widely projected as a top five pick after a career in which he started two years and was a first-team All-American by Walter Camp, Pro Football Weekly,, and first-team All-Pac-12.  Kalil is a big, athletic kid who needs technique work but has the potential to be a franchise tackle.
2. OT Riley Reiff, Iowa, 6’5 ¾, 313, 4.94 40
Reiff was a first-team All-Big Ten selection who had a great finish to a career that started out rough when he was in trouble with the law before classes began.  Some scouts have graded him as a tackle who can play either side and some as a guard.  His run blocking ability, size, and plays with a nastiness that coaches love.  Expect him to be taken as high as the top 10.
3. OT Jonathan Martin, Stanford, 6’5 3/8, 312, 5.29 40
Stanford’s Andrew Luck had a brilliant career and was in part due to the great play of his line, anchored by Martin.  Martin was a three-year starter for Stanford who earned first-team All-Pac-12 honors in 2011 and first-team All-Pac-10 honors in 2010.  He was an honorable mention All-Pac-10 selection in 2009 as he was among the better linemen in the conference as a freshman.  The 2011 AP second-team All-American showed good feet and lateral agility as well as natural bend and foot quickness.  His size and nasty streak are two things that have many intrigued and should help him come off the board in the top 15-20 picks.
4. OG David DeCastro, Stanford, 6’4 7/8, 316, 5.34 40

I mentioned the play of Stanford’s line with Martin and DeCastro was just as much of a key part in that as Martin.  DeCastro has been a star since high school where he played in the Offense-Defense All-American Bowl and then followed that up as a three-time All-Conference selection.  While he isn’t a great athlete he is a big, strong, dominating run blocker with intelligence and toughness.  Expect him to be a top 15-20 selection like Martin.
5. OT/OG Cordy Glenn, Georgia, 6’5 ¾, 345, 5.00 40
Like DeCastro, Glenn was a star in high school who also participated in the Offense-Defense All-American Bowl and became a two-time All-American for UGA.  Glenn is big, strong, and can play either guard or tackle.  He’s a very good drive blocker who is also able to get to the second level quickly.  When you combine his size, versatility, athletic ability, and consistency he is a definite first-round pick.
6. C Peter Konz, Wisconsin
7. OT Mike Adams, Ohio State
8. OG Kevin Zeitler, Wisconsin
9. OT Kelechi Osemele, Iowa State
10. OG Amini Silatolu, Midwestern State.
SLEEPER: OT Tom Compton, South Dakota
