Clingan is not one dimensional, his post moves around the basket have improved a bunch already and he's obviously great off of lobs. That doesn't mean he's perfect, the FT shooting has to improve even if it's a small sample of struggles. The defense too, to make sure he doesn't commit stupid fouls.
I'm not worried about Castle, there's no conclusions to draw yet off his 12 FG attempts about his offensive game hurting us. He's a capable shooter from outside, and that's the reason why he's able to drive so successfully and get shots at the basket. If he's getting the basket with ease I have no issue with a lot of his shots coming at the rim
