One point also, the game was very sloppy. Neither side played well, and sloppy games are tougher to officiate. I just thought the officiating was even worse than the game play.
I think that "1/16 of the ball" was his elbow and shirt - the problem on replay was you could NOT see where the ball was - therefore, the call stands.
I was pretty sure Roth got about 1/16 of the ball over the imaginary plane before being shoved back.
