2007 Illinois. We played pretty blah to start, but we got hosed on that long TD run that got punched out of the back of the endzone. I still don't understand why we get fucked over on a majority of the replay calls in our own stadium.
That was the first game that came to my mind. That was a dark, dark evening. The play you cite occured in the first half, right? The Buckeyes had time to overcome that call. I believe refs don't decide games (although I have had my doubts since seeing what that crew did to Wisky at Arizona St last year) - that players and coaches make thousands of decisions a game that outweigh the few dozen decisons refs make. But that particular call with the ball coming out and going thru the endzone seemed to be an obvious error, and definitely contributed to Illinois' momentum. Still, don't let guys get loose for 80 yards, and stop one play: QB draw.
We didn't lose, but the NC game vs. Miami contained several crap calls late in the 4th qtr. I contend that the game would have never gotten to OT without several terrible blown calls/non-calls. With under 3 min left in regulation, Ohio State had the ball, and came to a 3rd and 7. Gamble gets held twice on his pass pattern, Krenzel threw the ball low, and Gamble caught it for a first down. Ohio State gets a first down if: 1) either of the holding penalities are called 2) the catch is ruled complete. But, no holding and the pass was ruled incomplete. Ohio State has to punt. At that point, I think Miami only had 1 timeout. If the refs had made one of those 3 calls correctly, the Bucks could have run the clock out with one more 1st down, or would have punted with little time left. As it was, they punted, Miami got a big return, and they were able to send the game to OT. But on that punt return, AJ Hawk was blocked in the back as he zeroed in - as blatant a block in the back as you will see. If called correctly, that would have put Miami on their side of the field with about 2 min. Instead, they were in FG range after the return.
On the PI against Miami in the endzone, I'm still not sure whether it was PI. But I am sure that it was justice.
