He said that he hit his shooting arm with his left hand as he was going up.. it's possible there was a tiny amount of contact.. and that can really throw you especially on long threes..The ref's explanation on the Al foul on Wiggins' three was that Al moved his feet and violated Wiggins' landing space.
Which he did not.
Feels like the Warriors basically play the clutch, grab, hack system on defense and just figure they're not going to get called every play. C's did get a bunch of calls, but there were quite a few more they could have gotten.. and the OOBs calls all night were awful.
