He seems to have the worst luck on fouls.
I swear I did not see him commit four fouls. Maybe two.
Actually, of his 4 fouls, 2 of them were absolute crap b/c he was actually being fouled WHEN they called it on him...for the first, even the announcers said, "There is no way that can be a foul on Williams".
On the second foul, the aTm offensive player had reached back and was holding Amari illegally while trying to post up. Amari pushed the aTm's arms off of him, and gets the foul call. Amari did foul, but only b/c he was being fouled.
On the 3rd foul, aTm post player was trying to bull rush thru Williams, and he simply stood firm. He often has gotten into trouble using his hands when he's in good position, but he wasn't this time.
