Chism will be better suited if he learns some ball ball handling skills and a better jump shot. Plain and simple. Now, I am NOT saying that is what UT needs exactly. But, it would better chism a great deal.
Smith should have been groomed for the 2 position for the NBA. Witch means you can play him at the three, but teach him how to catch and shoot, and create his own shot. That is what will get Smith paid in the NBA. He will NEVER be a three in a league where his body is a 2.
What i'm saying is it would take a lot more work for him to "make it" as a 3. He's too slow to play the 3. He is big enough(would be better if he was bigger) to hold his own in the paint, even in the NBA.
