I watch the Bills of course, in the 1:00 window mostly, and if they win, I'll turn over to RedZone for awhile. If they lose, the TV goes off for the rest of the day.
I watch the Thursday and Sunday night games to help me fall asleep...maybe see 15 minutes of each, max. Especially hate how SNF has become "Football Night in America" with all the bells/whistles etc to rival a Super Bowl game in the 1990s. Al Michaels is a great announcer, but I've grown tired of him. Wouldn't mind seeing Tirico in the prime spot.
Have not watched more than 15 minutes of MNF this year, total.
I'm a Sunday Ticket subscriber, so if they've lost me, for a large portion of the TV schedule, I can't imagine the "casual" fan watching much of the NFL.
