After hearing from former refs and a few players, what he did wasn't all that bad. One ref Jerry somebody, who had more than 20 years as an NFL ref including Super Bowl appearances, said when a player comes on the field without a helmet, that's not necessarily a penalty. The refs take into account the game is an emotional game. As long as he's not mouthing off at another player and as long as when asked to get back, he gets back. And the refs said that's why Dez did when told to get back.
I don't know if anyone else saw this but after the game, there was a shot of the Cowboys walking back to the locker room through the tunnel. Dez was hyped. He was pumped as if he had scored the winning touchdown. I thought this was telling because he didn't have a big statistical game, but he was happy about the win and happy about his teammates' (T. Williams) success he couldn't contain himself. He wasn't pouting that he didn't have a bigger statistical role. I'm glad they showed that.
