i agree from a competitive standpoint, but from a purely TV standpoint i would be very surprised if this is not an afternoon game. the TV execs know they would not be getting much of the nor cal TV market if the game started at 9AM pacific, 11AM central.
I am betting the ABC game will either be Cal v Gophers or Arizona v Iowa the other B10 games aren't very thrilling that week and Mich v Notre Dame is on NBC of course.
Also, if anyone doesn't know about the NationalChamps.com website it is great if you are planning what to watch on any given weekend. They list every game by weekend and update the TV schedule as it is released.
