Hard to predict whether an outburst like Gundy's will make you a hero or a Mora. But my sense is that Gundy is celebrated for sticking up for his guy.
Yes, I read through the post Rich linked, which was written by a Browns apologist. I think Kosar went too far. Show some respect for the game and the people trying to make a living at it. He didn't. Ridiculing people on air is simply uncalled for, and everyone who matters (Kosar's employers, the Rams) agrees on that.
