WATCH: Rex Ryan Blasts New Buffalo Bills Head Coach on TV [VIDEO]

Welp, there's a reason the guy is on TV now. The former Buffalo Bills head coach, Rex Ryan landed a job with ESPN after his firing from Buffalo and on Sunday's NFL Countdown, Rex had his opinion heard about his successor.

Rex blasted at Sean McDermott's decision to start Nate Peterman over Tyrod Taylor in the team's loss massive blowout to the Chargers.

I think I can speak for the entire Buffalo Bills community, every fan regrets that dang decision that you made as a head coach. You might not regret that decision but everybody else does and understands it. Huge mistake. I don't know what the hell you're doing.
