I wouldn't say that Lee is amazing. No doubt he is perfect at what he does which is giving the team a lift off the bench and hustling and doing the work which most people avoid, but he isn't an amazing player yet. His defense could use some work. Just because he is a rebound machine doesn't mean he is a good defender. However, in a couple of years Lee will be one of the top hustle players in the entire league. If he can develop a good jumpshot he'd easily be the Knicks most valuable player on their current roster.
