It's Black Monday in the NFL, though some teams didn't wait until Monday (or the end of the season) to fire their head coach. Current vacancies:
Los Angeles Rams (fired Jeff Fisher)
Buffalo Bills (fired Rex Ryan)
San Francisco 49ers (fired Chip Kelly)
San Diego Chargers (fired Mike McCoy)
Denver Broncos (Gary Kubiak retiring)
I think we could see the New Orleans Saints job open up, I think the Rams could be interested in trading for Sean Payton.
