Yes, he's shooting 50% mid-way through this season, but he's a career 37% shooter, so there's no way he should be bumped THAT considerably. My ratings have him at a 75.
He's only shooting 37% for his career because he shot 20% his rookie year. He worked very hard during the summer and can easily knock it down. 75 looks accurate, maybe higher if he continues his good play.
I agree a raise is in order, but I won't jump the gun and make him the best shooter in the game. 62 does seem a bit low for what he's doing though so I agree with upping it to a more appropriate level.
