Between Brandon Knight and Dirk I'm not sure who looked worse in there debut, honestly Mavs are making a giant mistake giving Dirk any playing time over Maxie Kleiba who is the best defender the Mavs have, he leads the team in shot blocking and is excellent at switching, the guy if he can regain his stroke is going to get paid when his contract is up a 6'10 Plumlee type athlete with good instincts for the game I really like what I see from him on defense.
