The terrible call was to call the catch in the end zone "simultaneous possession." How could that be?! Jennings is a good 8-10 inches higher than Tate, the ball is clearly IN his hands before Tate touches it - then as they go to the ground Tate grabs hold of the ball with Jennings - but Jennings already has it securely in his arms and against his chest! It was clearly Jennings' ball that Tate was attempting to steal away.
The horrendously missed call was PRIOR to the catch - where Tate, with two hands, SHOVES #37, Sam Shields, out of the way! That's what REAL refs would call "offensive pass interference" which would nullify any chance or argument for Tate catching the ball. See for yourself:
