While neither was without fault, I agree with a foul on red.
I have to admit, since I started up again this is the call I have the most trouble with. Two players going for the ball and neither without fault...a play where the level of contact dictates you HAVE to have a whistle but on who. Until I get back into a better groove, see more, pick the brain of better officials, etc. I have just been giving the benefit of the doubt to the offensive player.
At least that way only one coach and half the gym is hissed off at me.
