I agree with pretty much everything you said. Except for the last part, Norman (a major trash talker) got in OBJs head, and he couldn't handle it, he snapped. I don't see anything wrong with the trash talk.
The actions of both players on the other hand were unnecessary and they took it to far especially when OBJ hit Norman helmet to helmet a good ten seconds after the play was over. I agree both should have been fined and suspended for a game but OBJ should have gotten ejected as well as the suspension.
Ah, football always starts some great debates haha, can't wait to see what next season brings. A Chargers SB win anyone? Haha I am thinking wishfully.
