That NFL TV Distribution site shows TB-BUF on in SW Ohio.

Very surprising - the Fox affiliate owners here most always go for games by teams that they think generates the most national ad profit for them.
My guess is that since one of their favorites - GB - is on the CBS channel with CIN on the road, and their other usual darling - DAL, is a Sunday night game, they settled on this.
I wait warily, though...if they think they can turn 5 cents more profit with another contest, they will dump the TB-BUF game in the blink of an eye. They have a history of switching.
