But now with a couple practices before the Huskers go into game week, offensive coordinator Tim Beck says there is a new player with the edge to start.
"Right now it's probably Justin (Jackson)," said Beck. "He's come a long way, it's part of it. Because he's such a young center, he's got a lot more room to grow."
A senior, Jackson has had trouble finding his position on the team. Just last year, he was playing on the defensive line.
"It's been pretty impressive his want to and what he's been able to do in a short matter of time," said Beck. "They are all still battling for playing time in that first or second spot, but we are slowly starting to work some guys who have an advantage here or there."
With the Big Ten being a heavy defensive tackle league, the center position will come with plenty of challenges once conference play begins.
"I think it's really important. You have to hold your own against top notch guys," said Beck. "Everyone has them. Just last year, Michigan State, Ohio State, Penn State, Michigan, all had them. Iowa had them. They are all really good players. You have to have guys who can hold their own."
