"When you're in the thick of it you always feel like they're singling specifically you out," Roh told GoBlueWolverine, "but it was every guy on the team that was being singled out. As I've matured more as a person, I know it's just for my benefit. Whenever they're hard on me, whenever we have a bad practice and Coach Mattison comes in there and is just doing what he does, it's only because they want us to be better and they want us to be the best players possible."
For Roh, the difference between last year and this year is huge.
"It's day and night," he said. "Just technique wise, hustling to the ball, just working through really any adversity. It's just day and night. I'm actually liking camp right now, it's fun improving everyday, and it's just a great opportunity this year."
"It's not always going to be fun, change is not always fun but winning Big Ten championships is fun, winning games is fun, having a great defense is fun—and that's something that they really want for all of us," said Roh.
Part of the change for Roh is the move from weak side defensive end to the five technique, strong side defensive end. After spending the winter putting on a significant amount of weight, and the spring learning the position, Roh feels like a natural.
"I love strong side defensive end," said Roh. "I played it in the spring too, and so I got a glimpse of it there, and I just love it. It's great because I'm moving as fast as I ever have at 280 pounds and I think I'm quick in small spaces and I can get after the quarterback at the three tech and five tech, so I think it just lends itself to what my abilities are."
Versatility and leadership along the defensive line were major keys to the success the defense shared in 2011. Roh is looking to follow the same path.
"Every guy on this D line, I just care about them so much and really want to see the best for them," said Roh. "I think that's really what Ryan and Mike wanted last year—was for the D line to be as good as it possibly could, and I want the same thing for this D line. Those guys were great leaders last year and I hope I can fill that role."
Another defensive lineman hoping to fill a role and then some is Michigan senior defensive tackle William Campbell. Roh believes this is the former high school All-American's time.
"Will's a guy that's ready to step up this year," said Roh. "He's worked his butt off this summer and he's having a good camp. We still have a lot more practices, and he's really just ready to improve everyday and that's something that I just think indicates he's ready to have a great season this year."
Picked by the media as the favorite to win the Big Ten in 2012, it seems everyone is expecting the Wolverines to have a great year. With Alabama and a dominant offensive line looming in front of Roh and Michigan, a fast start to the game will be the key to a tremendous start to the season.
"They're one of the best and that's just honestly how it is," said Roh. "We need to come in everyday, we can't have a bad practice, there needs to be a sense of urgency because we have Bama, defending national champions, first game. If we come out there and don't play our best we aren't going to be able to come back because they're a very good team."
For Roh and the Wolverines, the goal for the 2012 season goes way beyond just one game on September 1st.
"Just a dominating defense and winning the Big Ten championship," said Roh. "That's the goal every year."
"We have a long way to go right now and we have a lot of practices to get through and to improve but we've got the guys, we just need to get it done," he said.
