Why is Westbrook allowed to take a shot? Sure, he scored 31 but it took him 28 shots to get there. He went 36-100 for the whole series to get 118 total points. He's just a really bad shooter.

His biggest problem is that he's selfish. He takes terrible shots when he should be passing the ball. His poor shots take shots away from good shooters like Harden.

Another problem of his is that he shoots the ball like he's always expecting to get fouled. Then, the defense pulls away and he ends up taking a weird contorted shot for no reason. Then he bitches about not getting a foul called.

He has a terrible attitude and it hurt his team tonight especially on his technical foul that started giving the Mavs some momentum. Plus, he was only one technical foul away from having to serve a 1 game suspension. How good would he be to his team then?

He should only be allowed to shoot the ball when he drives, and then only if he shoots it normally and not trying to draw contact. If he gets fouled, then fine,  but don't aim for it. 

In this series, Durant took some really awful shots away but is a way better shooter than Westbrook, and Harden looked like he might be able to play PG better than Westbrook. Harden should start with Westbrook coming off the bench. But that would likely shatter Westbrook's tender and enormous ego.
