I fully support Cousins in this situation. Wanna know why?
1. Tyreke and Donte were laughing after Tyreke missed the shot. LAUGHING AND SMILING?! Really?! You just lost another game, and you are laughing? Would Kobe be laughing and smiling after missing the game winner? MJ? Cousins is a competitive kid, he hates to lose, he had been fouled on the last play, he thought he should have gotten the ball, and then he sees Tyreke and Greene laughing after another loss? No wonder he got pissed off.
2. From the reports, Cousins began to back off in the fight, but Donte kept going at him. Sounds like Donte wouldn't let it go and that resulted in the fight. Why are we saying "Cousins shouldn't fight a teammate"? Why don't we consider the fact that Donte could have been pushing for a fight more than Cousins was? Of course it was idiotic of both of them to fight, but why is Cousins the only one receiving the blame?
Teammates have scuffles all the time, anybody who has played competitive sports would know that. It happens all the time in the NBA as well, and more losing is only going to instigate it more. Try to look at things from Cousins' perspective: a 20 year old kid who hates losing, who loses again because terrible shot selection by a terrible 3 point shooter (The only 3-point game winning shot Evans has made was a fluke 70-feet shot), witnessing the very player laughing and smiling right after the shot.
