Albeit a small sample size (one game that I saw), but Keller appeared more athletic than Dinos. He's MUCH quicker off the floor. Really explosive to the rim, both offensively (dunks) and defensively (rebounding). I always thought Dinos' game was a bit choppy, and he had a very European release with his jumper. Keller is REALLY smooth with the ball. Good feet. Just looks like a kid that's comfortable anywhere on a basketball court. Really smooth shot from outside too. I understand he has been reworking his outside jumper, taken it from more behind the head to more in front of his body. It looks really good. He looks a lot like Jake LaRavia, to be honest...needs to bulk up in the upper body, but a kid that can really do a lot.
Not sure where we'll be next year roster-wise, but I won't be surprised to see Zach eating up major minutes at the 3 and behind Jake at the 4.
