Oregon at home would be ESPN or CBS too.
Home team has rights, and the SEC has no contract to play on ABC.
And don't underestimate the value of an entire days focus on national TV in a game involving Tennessee on recruiting, let alone that we have to generally have become a power to get it.
Other games the same day involving current top teams...
South Florida @ Florida (CBS/ESPN) - Best guess = ESPN @ Noon
Iowa State @ Iowa (ABC/ESPN) - Best Guess = ESPN 2 @ Noon
Virginia @ Southern California (ABC/FoxSports) - Best Guess = ESPN2 @ 3:30
Miami(Fl) @ Ohio State (ABC) - Best Guess = ABC @ Noon
Penn State @ Alabama (CBS/ESPN) - Best Guess = ESPN @ 3:30
Wyoming @ Texas (ABC/ESPN) - Best Guess = ESPNU @ Noon
Michigan @ Notre Dame (NBC) - Best Guess = NBC @ Who Cares(3:30)
Miami(Oh) @ Cincinnati (ABC/ESPN/BigEast Network) - Best Guess = BigEast Network @ Who Cares(7:00)
Toledo @ Boise State (ESPN) - Best Guess = ESPNU @ 10:00
TCU @ SMU (ESPN/CBS College Sports) - Best Guess = CBS College @ Who Cares(3:00)
LSU @ Vanderbilt (ESPN Regional) - Best Guess = ESPN Regional @ 12:30
Georgia Tech @ Kansas (ABC/ESPN) - Best Guess = ABC @ 3:30
Pittsburgh @ Utah (Versus) - Best Guess = Versus @ 4:00
Tennessee vs. Oregon gets the night slot on ESPN... and a decent chance at Gameday along with Penn State @ Bama, and Miami @ Ohio State.
Lot of good games that weekend... but bear in mind CBS doesn't usually start broadcasting college football until week 3 or so due to the US Open.
Reasonable chance Boise, Cinci, or Utah is moved to Thursday.
