Josh just powered through the dunk, threw it down and then stared down the ref and started complaining about the foul.
when you watch the play, i really don't blame the ref, it doesn't look like Ilyasova fouled Josh because Josh just powered through it like Ilyasova wasn't even their and it happen so fast.
Josh likes to complain alot about getting fouls, but at the same time, he doesn't sell it like alot of the NBA stars (like what McGrady use to do

on that play Josh could have defiantly given a little yell as soon as he felt contact from Ilyasova, and then pretend to stumble a little when he landed to show off to the ref to indicate that Ilyasova pushed him hard enough that it made him lose his balance and merits a whistle.
