People close to the Grace program have told me laziness is a problem for McMasters, but I've seen him work fairly hard in games, especially on defense. I think his offensive struggles are related to the freshmen and sophomore guards on his team being unable to get him the ball in good positions. At 6'10" he's unable to create his own shots, so his effectiveness is going to depend a great deal on the ball handlers. Against Temple Grace's guards struggled to cross half-court with the ball, much less find Carter where he could score.
