According to the Trib's ASU football notebook, the ASU/USC game at Sun Devil Stadium, currently scheduled for November 17, could be moved to Thanksgiving, pushing the au game back to December 1.
I'd be all in favor of this move. We already know that the last five weeks of the schedule are brutal (Cal, @Oregon, @UCLA, USC, au) so adding a bye week could only help. Plus, the TV exposure would be significant.
According to a few posts on various message boards, there is some confusion as to whether the proposal is to move the game to Thanksgiving Day itself, or to the Saturday following Thanksgiving. Either would be OK from my perspective.
Keep in mind that in 2007 Pac-10 games will be split between ABC, Fox Sports Net and ESPN, so expect the conference to move several games to non-traditional slots.
Typically the pre-season selections for TV games are announced in May/June, so it may be several months before anything is confirmed.
