I am NOT a football ref, but I've reffed just about every other sport. I was wondering why, in the NFL, a coach never gets ejected? I remember a game a number of years back that Bill Cowher was ticked because the refs missed a 12 men on the field call, so he ran out and shoved a picture of the field into the refs chest pocket that showed the violation. Are they protected by the league from ejection? Has an NFL coach ever been ejected?

I believe the only thing that warrants the ejection of a coach is if they contact an official.
