One of my worst ever losses was at the very beginning of the college football season this past year... Villanova vs UMass. I had Villanova +5. Nova goes up by 8 early in the 4th w/ a TD pass to make it 21-13. With 6:30 remaining UMass cuts into the lead with a FG, making it 21-16 Nova. With 4:00 min to go, UMass scores a TD and fails the 2 pt attempt, making it 22-21 UMass. With 1:51 left, Nova hits a FG, making it 24-22 Nova. UMass puts together a nice final drive and gets in FG range in the waning seconds. UMass hits the FG, making it 25-24 UMass with 0:03 on the clock. UMass kicks off, and Nova of course begins lateralling. During this process, there were probably 2-3 forward laterals committed by Nova. Flags were flying all over the field, but the game is still live apparently, kind of like when the DEF is offsides and the offense gets a Bonus Play. Finally a UMass guy running full speed steps in front of one of the laterals and waltzes into the house. The commentators even said something like, "There are flags all over the field, but it won't matter, this game is over," before the play was finished because of the shit load of forward laterals. They announced the final as 25-24 UMass & the broadcast immediately cut off... the game was on ESPN or ESPN2. I pulled up the gamecast on my phone, and it was showing a 25-24 final. I checked ScoresAndOdds, and it had a 25-24 final.
I continue eating my lovely dinner with my girlfriend, thinking I had hit my only play of the night (it was a very slow sports day, hence why it was on ESPN in primetime in the first place). It must have been about 2-3 hours later when I got home and flipped on some Sportscenter, and I noticed the bottom line showed a 31-24 UMass final. Basically the refs convened after the broadcast had cut off & after the announcers said the wrong final. The final TD counted and I was in utter disbelief. I've taken worse beatings as far as crazy shit happening at the end of a game... but to combine that craziness with the fact that the f'ing final score was incorrectly announced/posted on multiple websites, it was just such a devastating loss.
