The list of available TV windows are based on media websites, TV listings and press releases. They can change based on the needs of the broadcaster or the conference.
Here's what I guessed based on the available openings (they will prove to be incorrect) and here is the current schedule for the week as several FBS games do have their time & television/webcast assignments already accounted for.
The number of six day holds available for each conference
ACC: 3 (10/12)
American: 3
Big 12: 4
Big Ten: 3 (10/12)
SEC: 3
Pac-12: 4
All times Eastern
Games on hold
Florida St. at Clemson - ABC at 3:30pm or 7:30pm
Penn St. at Iowa - ABC, FS1 or BTN at 7:30pm
Nebraska at Minnesota - FS1 or BTN at 7:30pm
Michigan St. at Wisconsin - ABC or BTN at 3:30pm
I think these are the possibilities for the three B1G games plus Florida St.-Clemson on 10/12. pic.twitter.com/ZOx0wpLKeM— Matt Sarzyniak (@mattsarz) September 30, 2019
