I have several "favorites:
1. In the 1979 tu game the Ags kicked off with the Sun directly behind the kicker. He kicked it in a high trajectory angled. One of tu's Jones boys went over to the tu sideline to take kick, but he didn't have a clue where the ball was going because he was blinded by the Sun. He signalled for a fair catch, but the ball bounced off of him toward the tu goalline. A&M recovered around the tu 15. Ooops... the side judge blew his whistle when he saw Jones raise his hand.
"Inadvertent whistle" ! tu kept the ball. Tom Wilson wents postal. The Ags won anyhow, depriving tu of the Sugar Bowl.
2. In the 1997 Navy-ND game, the Navy QB, Chris McCoy faked a handoff to the FB who was gang tackled after three yards. Meanwhile McCoy smoothly pitched it back to the right slot back who turned up field with nothing between and the goal line but 60 yards of grass. "Inadvertent whistle" ! The field judge (and the entire ND team) thought the FB had it. No TD. Charlie Weatherbie (then Navy's head coach) went postal on the sidelines. Navy lost 21-17 ... again.
3. Same game ... Navy was ahead 17-14 with less than two minutes to go. On 4th and nine, ND passed and the receiver was brought down a yard and a half short of a first down. The head linesman spotted the ball terribly and then measured it. First down, Notre Dame. Even the ND's homer broadcasters on both TV and radio said it was a horrible spot. They scored six plays later. Navy didn't quit though. They threw a long desperation pass that got stopped on the ND 1 as time ran out.
4. In the 2000 OU game, Mark Farris threw one of his all-too-frequent game-deciding INTs. He ran to try to tackle the interceptor. OU's outstanding LB, #11 (whose name escapes me for the moment) pushed Mark to the ground from behind, one hand on Mark's #1 and the other on his #0. If ever there was a "Blocking from behind above the waist" call, that should have been it. NO CALL. TD scores. Ultimately it was the winning margin for OU.
Gig 'Em, Aggies !!
