IMHO, Too many sport on TV anyway. The NFL is oversold.
I’m done with sports till February when NASCAR starts again, and then Baseball.
After the NFL on Thursday night, some college games on Friday, college games from noon to past midnight on Saturday and two rounds of NFL games on Sunday afternoon maybe people are just a little overdosed on football by Sunday night.
If there were 24 hours of zombie shows before the Sunday night showing of Walking Dead it might suffer in the ratings too.
