Nope. I think Crowder was trying to catch up to Hayward to try to blow the alley-oop more than anything. The only thing he did was latch onto Hayward's arm. This was just a freak accident which happens every now and again. However, a foul absolutely should have been called.
How can you tell the look on Crowder's face was a laughing smirk? It looked to me more like a grimace, but I don't think anyone can tell from that camera angle, which was too far away, to make out Crowder's facial expression.
