Just FYI, Willis's stats against Rice his fresh and soph years:
2006 at Rice: 8 for 19 (42%), 137 yards, 1 TD, 2 INT, 45.2 QB rating. SMU loss.
2007 at SMU: 13 for 31 (42%) 165 yards, 4 TD, 2 INT, 71.9 QB rating. SMU loss.
Throw in the fact that JJ believes Bo Levi can execute his offense better than Willis can and I'm not so sure that our chances to win vs Rice have changed much. Remember that EITHER QB, learning a new offense, will have a few bumps in their first few games running it, not solely the true frosh.
