I know he's a rookie, but seriously what does Rivers provide this team out on the court? He doesn't seem to do anything on offense. He currently is in a terrible shooting slump, but he's not even trying to drive to the basket and get to the line. If you aren't shooting well then you have to figure something out which you can help the team with on offense. Just dribbling the ball around a bit and then swinging a pass around isn't really doing much.
If you go by this game, he's a shitty player, but he has ben driving to the goal laying it in, getting fouled and stuff like that.
