Pensick and Long were probably the best Lineman we had last year, especially Pensick by the end of the year. I remember an interview, maybe after Iowa, that Pensick was regularly grading out the best out of any lineman. We aren't going to lose much if nothing at all at Center (Jackson was spectacular at pulling). Cotton looks to be an absolute mauler with an attitude, something we haven't had since Henry graduated.
I like how the OL is shaping up, and if they can just get good play in pass protection from the tackles, then we have a top 10 unit in the country to go with all the weapons at the skill positions.
