Agreed on the atttitude Dez displayed in the Seattle game. The team was winning and offense was operating efficiently ... but that wasn't enough for him and it clearly distracted the team by the number of players.
Making matters worse, when they did throw to him, he was so determined to make a big play that he carried the ball in his inside left hand like a loaf of bread, making it easy for the defender to knock it loose. The rest was history.
