Their fans are confident, but I think they respect that BYU can actually play with them. It felt that VCU had a lot of posts about how they were going to out-athletic us and that we had never seen a defense like theirs, etc.
Wisconsin has a few guys (faceFuzz) who are very confident that BYU is not going to challenge them much. But most of their fans seem to at least acknowledge that BYU could come in and compete with them. There is one post I think that still is somehow trying to suggest that teams just need to follow the Houston plan. Good luck with that.
