I don't think BigFun meant to lay it up as aggressively as he did, but once he rolled to the basket (special thanks to Kawhi Leonard for providing beautiful interference on Pau Gasol) and found himself all alone at the rim, he had little choice. As Sean Elliot said, "I think Tim surprised himself".
[Editor's note: I can't remember the last time Timmeh dunked off an alley-oop. It has to be five years ago or more. -jrw]
