I don't really think that his jersey should be retired. He has brought a lot to the program, but it takes an exceptional level of greatness to have your number put up there. Zac is a good quarterback, a good leader, and also a team player. He helped NU get back on its feet after 2004. His 1st year statistics are kind of shaky, but this year is pretty good. I wouldn't retire his jersey because I can't put him on the same level as quarterbacks like Tommie Frazier or Eric Crouch. I appreciate what he has done for the program and NU would be a different team now without him. I would be for retiring his jersey if they win the Big 12 this year and win the Fiesta Bowl.
