I see nothing but a smart play here.
Melo doesn't play above-the-rim; he only has 7 dunks across 71 games this season.
Which begs the question - what could he possibly have done to get up a shot against two bigger, more athletic defenders right on his hip? Duren was all ready to jump and punch his shyt and since Melo is well aware of his own limtiations at the rim, the best course of action was to fake out both defenders and then find an open shot.
I get the critiques around his style of play that he plays too much, but he made the right decision on this possession.
