This week we've begun ranking the five best players at each position in the history of the Big 12.
A couple of notes: We'll be basing these lists on the college careers of the players, not on how they fared in the NFL. And we've only considered players that wore Big 12 logos at the time they played.
We continue this series below with the offensive line:
1. Jammal Brown, Oklahoma (2001-04): After signing with the Sooners as a defensive tackle, Brown emerged as one of the finest offensive linemen in Sooners history. Both protecting quarterback Jason White's blind side and paving running lanes for Adrian Peterson, Brown was a unanimous All-American and a three-time All-Big 12 pick.
