Jason Peter was a consensus All-American defensive tackle in 1997, one of the most ferocious Nebraska players in program history.
But he can't remember ever drawing a personal-foul penalty.
"I think I had an (incidental) face-mask penalty in 1996 against Colorado that was questionable," he said Sunday.
At the root of his restraint was accountability to teammates and coaches, an area the current Husker program is striving to improve.
"We knew that, No. 1, you were going to have to get back in that huddle and look at all the rest of your teammates who were busting their tails to try to get off the field or try to make something happen," Peter said.
