What's the rule on hitting someone in the face when they are shooting?
Seriously, this is a non issue. There are always calls missed both ways. let's not forget that Hield should be able to pass by around a 5' 10 player. It was a bad pass by Hield and a good play by Mason. It was a great game by both teams. Leave it at that.
To make the play even worse, using randoms statement that it was the last jump during the pass when he crossed, mason was the first to touch the ball while being out of bounds.
So, first, he is too close, then crosses the outofbounds and then makes contact with heild, then makes contact with the ball while out of bounds. A major mess up by refs.
