I like it, take pressure off from the refs, they don't have the luxury of watching plays in slow motion. Call it as you see it, the office will adjust accordingly. By presure alone a ref might feel inclined to call or change a certain play to appease the home team.
This is a good guess, but if it were to be the case they shouldn't show the slow motion replays live or on the stadium screens.
you either have control or you don't, I thought it was good call, Ryan had no control after Hughes hit and then pushes the ball forwards.
