either that, a guy who just knows how to play through the contact & get it off the glass in a variety of ways. Neither Caleb or Fouss play above the rim (that is, both have to gather themselves a bit & get on balance to dunk). I think both in time will get the reps & touch to be high percentage pick'n'roll options (particularly Fouss), but right now it's not a high enough percentage shot for either to run the risk all too often — of a deflection turnover or an offensive foul.
For Atiki, though --like Gavin-- that could easily become a very high percentage shot for him if he continues to work on it. Also, with his smaller role, it doesn't hurt as much as it would with Fouss or Lohner — if he picks up a foul in the process. It's certainly something worth running while he's in.
