Yeah, I just heard Chris Fowler mention that last night during the Raiders/Falcons game.  I thought "Wow, that's weird."  Can't remember the last time I watched a cfb game on TNT.  And a playoff game, at that.  
YTTV has TNT so you should be fine.  
Correct me if I'm wrong, wasn't it you I was talking to a year or two ago about cord-cutter services like YTTV and you were telling me that your cable bundle with internet still made it well worth your while to use them?  (Spectrum, maybe?)  Because I think it's the same company we have here (Spectrum is the only cable option here) and I remember thinking "Pfft, Spectrum sure doesn't run any deals like that 'round here."  If that was you, what made you jump to YTTV?
