Just for fun I decided to rank the college offensive lines. I used Football Outsiders rankings.

I averaged together the 5 rushing categories to try and determine how effective a teams offensive line was when rushing. I also added in the number of Ranked OL the team has, based on CBS for this upcoming draft along with next years draft. I included an average OL ranking as well. This is to get a sense of how many offensive lineman are projected to go to the NFL. Or at least those that were ranked.

Wisconsin had the best run OL. They ranked 5th overall. They have 4 guys that are projected to the NFL with an average ranking of 19.25.
Tyler Marz OT 5.00
Rob Havenstein OT 12.00
Ray Ball OG 23.00
Dallas Lewallen OG 37.00
Followed by Alabama who was 11th and Nebraska who was 18th. Both teams projected to send 4 guys to the NFL.
PLAYER POS. POS. RANK SCHOOL
Isaac Luatua OG 6.00 Alabama
Arie Kouandjio OG 7.00 Alabama
Austin Shepherd OT 15.00 Alabama
Leon Brown OG 45.00 Alabama

Alex Lewis OT 15.00 Nebraska
Ryne Reeves OG 18.00 Nebraska
Zach Sterup OT 31.00 Nebraska
Jake Cotton OG 51.00 Nebraska
This supports my contention that Coleman, Duke Johnson, Langford and Buck Allen all had inferior offensive lines to that of the top 2.
One thing that really stands out is Mike Davis. I've been back and forth on this guy, but with the offensive line that he has, he should have been much more productive.
