I forgot who posted it or maybe it was a tweet but "Steph thinks he's SGA but the refs don't" was very on-point.
It's a fair point... but at some point after the 10th non-call and getting your shit rejected, the blame goes on the player for continuing to go back to that well. Steph also sucks at FTs, so it's not like getting to the line is even the most efficient use of a possession either
[Note: I'm actually not this down on Castle, I'm playing a bit of a devil's advocate here... my preference is that we keep all 3 of Fox, Castle and Harper and just... you know... use them correctly]
