Nothing really major. He had us wear black jerseys on Halloween (I didn't think they were that bad but only for 1 game a year at the most). Another thing he did was have the players wait around in the tunnel before running onto the field. In previous years and after he left they ran out as soon as the T opened up. With him they stood around forever. I don't really know why he did it but it I think it is a lot better before/after kiffin. You can see the difference in these videos.

Also he moved the Vol Walk up to right before kickoff. The Vol Walk is when the player leave the bus and walk down the street for the games. I didn't go to any of the Vol Walks while he was HC but everyone I have heard comment about it said it was better when it was done further away from kickoff. (like it is now and before). He didn't do anything major but he did some things that a lot of people didn't like. He never really seemed to care at all about any of our traditions either.
