We are talking about a five-year gap in age/experience and Durant is already at least noticeably better. Durant's D and rebounding are getting better. We saw what he could do on the glass in college, I always thought that part of his game would take time to mature. Melo mostly sags off and grabs defensive boards, Dirk Nowitzki-esque. I could see Durant becoming a very good defender but like all offensive stars he'll have to manage his exertion at that end to stay fresh.
