"It's football, we can't control anything like that. All we can do is do what we're asked to do and go out there and play our hardest to give the best effort so we can give the team the best chance to win. We can't take that call back, so we suck it up and we move on."
Somehow I don't think that's what the animated Peters was saying to the ref here.
Re-watching this game (I know, awful decision by me), it could be argued that this was a make-up call for a missed pass interference call on Sean Smith the play before.
I would say it's probably a good thing that Peters didn't talk to the media after the game.
