I went through and looked at the timeslots already scheduled along with the games available to be picked up. Here are the games that still have to be determined:
B12 games:
Oklahoma St @ Kansas St
BYU @ Baylor
TCU @ Kansas
Iowa St @ Houston
Colorado @ UCF
Cincinnati @ Texas Tech
Big Ten games:
Illinois @ Penn St (5 PM MT kickoff)
Wisconsin @ USC
Minnesota @ Michigan
Oregon @ UCLA
Nebraska @ Purdue (10 AM MT kickoff)
MWC game:
Washington St @ Boise St (Fox/FS1)
The WSU/BSU game will be on either FOX or FS1, but the exact network and time isn't determined yet. 1 of the Big Ten games will be on CBS and 1 of them will be on FOX. It's possible that 3rd could be on FS1 but not guarantee on that. The rest will likely be on BTN. The B12 will likely have 2 network games (FOX and/or ABC). They'll have 3 or 4 more on ESPN, ESPN2, or FS1, and then have 1 or 2 on ESPN+.
Here's the current available timeslots:
10:00 AM FOX
10:00 AM ABC/ESPN (opposite Kentucky @ Ole Miss)
10:00 AM FS1
1:30 PM CBS (this will be a B1G game)
1:30 PM FOX
5:00 PM FOX
5:00 PM ESPN2
5:00 PM FS1
8:15 PM FS1
I'm going to guess that Wisconsin @ USC gets the 1:30 PM CBS slot. I would think that Oklahoma St @ Kansas St is the frontrunner for the 10 AM FOX slot with Big Noon Kickoff attending. If that happens then I'm guessing Illinois @ Penn St gets the FOX primetime broadcast. That would leave the 1:30 PM FOX slot for another B12 game. It's possible that BYU/Baylor could be the pick there, but my guess is it ends up TCU @ Kansas. That would leave either the 10 AM ESPN and FS1 slots or the 5 PM ESPN2 and FS1 slots for BYU @ Baylor and a few other games.
In Summary:
BYU @ Baylor game will likely either be @ 1:30 PM on FOX, or at either 10 AM or 5 PM on ESPN/ESPN2/FS1.
