The DL has been overachieving, for the most part. We rotate a lot of guys on the line. At the beginning of the season, the line suffered a rash of injuries. Lawrence Wilson was supposed be the guy but broke his leg in the first game of the season. Remote chance he might be back. True freshman Cameron Heyward (son of the late Craig "Ironhead" Heyward) has taken over for Wilson and has been a huge surprise and difference maker. Plays well beyond his years. Dexter Larimore is a RS-freshman who has really come through at the tackle position.
Tressel's philosophy is based on the minimizing mistakes, and as such will run the type of offense which best suits his players' abilities and level of experience. If he can trust his QB to get the job done, he'll let him sling it all over the field like we did a couple times this year and all of last year. If the team commits turnovers and makes mistakes, he'll go back to pounding the ball away on the ground. Tressel doesn't run a "system" per se. He runs what he thinks is best for the personnel he's got that year, and as such will change the offense to play to those strengths.
And as for uniforms, I say we wear the road whites so we force LSU to put on those gay purple jerseys.
