There are a lot of possibilities left for the Wisconsin game:
11:00 BTN - TBD (Northwestern at Purdue possible)
11:00 ESPN - TBD (Northwestern at Purdue possible)
11:00 ESPN2 - TBD (Northwestern at Purdue possible)
2:30 ABC -
2:30 ESPN -
2:30 ESPN2 -
6:00 ESPN2 -
6:00 BTN - Ohio State at Indiana
7:00 ABC - USC at Cal
7:00 ESPN - TBD
My guess is that this will be one where they do not announce until 13 days before the game. This is because there are two other games that have yet to be scheduled which could be very good (Penn State at Illinois and Michigan at Michigan State). It all depends on teams' W/L record and ranking coming out of the 3rd week of nonconference play.
Arkansas State is at Iowa on that date, so there is at least 1 game we are guaranteed at getting a better time slot than.
My suspiscion is that Iowa/Arkansas State will get places on the BTN at 11:00 am, Northwestern at Purdue will be on espn2 at 11:00 and the three remaining games will fight it out between ESPN at 11:00, ABC at 2:30 and either ESPN or espn2 at 2:30.
