You can tell it is working. Numerous offensive linemen are competing for playing time this Fall, as perhaps UM's weakest unit last season has one year of experience in Coach Rodriguez's system under their belts.
Coach Frey spoke with the Freep, and while he didn't reveal any starters, he did say that he is pleased with the level of competition brought by his players.
"On any offensive line, it's about the system," Frey said. "You can talk about cohesiveness, but it's the five starters and the guys who can come in and play at that level as a starter."
"If I can play 15, I'll play 15," he said. "Usually the hardest position to substitute is the center because of the snap and the cohesion with the quarterback. At the guard and tackle position, that's the spot where four or five guys are ready to play. Sometimes injury answers that question for us."
Frey indicated that now that they understand the system, it's time to take it to another level.
"It is something that's nice where we get an opportunity to continue teaching and take it up another level," Frey said. "There's a comfort level. It's nice seeing those faces. We'll see how it ends up with starts and who goes in there. They're all committed."
Perhaps no group on the Michigan team has more to prove, and perhaps none is thirstier to compete.
