head fake that got a defender in the air and no longer in control of whether he fouls or not is just classic basketball to me.

Now, jumping sideways into a guy not so much. That wasn't part of the classic head fake/foul play, but Luka didn't jump sideways last night. He jumped towards the basket. That, to me, is just classic basketball and if you don't want to be called for a foul, then don't leave your feet and jump towards a shooter. Towns didn't even jump to the side of Luka, which is what "good" defense is supposed to be these days. He jumped right at him and Luka took advantage. That's just classic basketball to me.
