When you REALLY want to get someone back, the last thing you do is announce it to the press.
You just make sure someone is the victim of an unfortunate play during a game. Just one of those football accidents -- get it?
But if you make talk too much, either you're just blowing hot air or not very bright because you'd be the one getting a suspension -- not the douche bag who elbowed a running back in the head while he was down and then celebrated his concussion.
