NASCAR can't really be listed in this discussion as thier Races are spread out among multiple channels.
ESPN, FOX, TBS and I might be missing 1 or 2 ...
Fox, (may be 1 or 2 races on FX but I'm not sure anymore) TNT, ESPN/ABC
I quit watching once football starts and its coverage has gotten so boring and long the last few years, that I mainly dvr and scan through the races when I do watch. That's another problem is they no longer just give good coverage of the events, they want to show a bunch of human interest stuff, then some social media add in, etc.. Just show me the game and give me some good play by play, I don't need all the other crap, especially at the prices we're having to pay for the privilege of watching now.
