Mathis took a leave of absense from the team during the season. Kim and co. said he was as good as gone and got everyone all riledup against Petersen. Mathis of course came back and it never came out why he left the team or where he went.
Mathis had a weird recruitment too. He committed to UW early, then got a bunch of offers and decommitted. In the end, his other offers seemed to all dry up because no one thought he would get into school and he came back to UW
