You are right that the refs were not calling the push offs by VT WRs. It was very frustrating.
Though, what likely was hard for you (and Narduzzi) to see (because you were at the game and not seeing the replays) is that Pitt's DBs were often grabbing onto the jersey of VT WRs. What was puzzling was that it often didn't seem like it was even necessary. It appeared as if they could have just as easily put a hand up to try to make a play on the ball.
It's very possible it looked more one sided to Narduzzi too, as he was not able to see all of the replays. Pushing off on someone is easier to see, since the defender's body quickly moves away from the WR. Bad officiating indeed. Many calls were missed on both sides.
That's the thing. The were bad for both teams. But there have been way too many blatant calls missed in ACC games this year....in every game. That can't happen. I know it is a hard job and they are human, but you can't miss blatant calls out in the open, like facemasks or holding calls where the defender's jersey is being ripped from behind. The complaint is how inconsistent they were. No one knew what a penalty was.
