I didn't see the call as wrong or correct. If we were on the other side, and a PI was called, I feel like many on here would have argued about the call and wanted it reversed. In this case, the call didn't go our way. As a coach, I never let my players blame refs for the outcome of the game (and most posters don't seem to be blaming the loss on the refs, but some are hinting at it).
Play through adversity, through refs, and play the game. We had chances to win, and some would argue we actually had more calls go our way than Wisconsin.
I think that's a lot of it. It's one of those plays that's close enough it could go either way. Probably gets called a lot. Doesn't get called some times. If it goes your way, you think it's the right call. If it goes against you, you tend to think you got screwed.
Watching it a few more times and really slowing it down. I think Westy slowed down to try to cut underneath Watt. But they clipped knees as Westy cut made his move and that's what tripped him up. You can tell by the way Westy fell that there wasn't much contact in the chest/shoulder area. If that would have been the case, Westy would have been knocked back. Instead Westy's torso keeps going forward but his legs kick out from under him. Officials are also more inclined to let leg contact go as incidental. I think that combined with the pass not being really close led them to pass on the call. Again, I'm not saying that is right. Just that I think an argument can be made for why they did what they did.
The real shame is that TA won't check to a second option. He double-clutches as he sees Watt dropping into that zone but still tries to fire it in there. Had he come to the near side, it would have been an easy throw to Reilly who had a smaller defender posted up on a curl route.
