"When he's playing a stretch-four, it's a little more difficult because he's coming from the outside all the way to the rim. But if he's covering a more traditional power forward, someone near the rim or not too far out, he covers ground. Off the ball, in his first year, he's elite. The NBA stats will confirm that rim protection. But that's off the ball. On the ball, he's 215 pounds and he's guarding centers or even 'four' men that have 20 or 30 pounds more on him. We have to teach him technique of the NBA where he's using arm bars [forearm on opponent]. We have to teach him to better front to get him out of those weight problems [getting backed down]."
