I have never left the stadium angrier than I did after the horses*** safety call in the end zone against UNC. Nothing is close to that.
2003 BCU game is up there too. By that point, we knew this would be the only game UConn would ever play against Boston College at the Rent. There was a bizarre clock malfunction in the first half, where the clock stopped on 1 second a good 3 seconds before the play was over, giving BCU time to kick a FG. Then Keron Henry drops a sure TD catch on the 10 yard line that turns into a missed FG. UConn loses by 10, with the ball, deep in BCU's end.
The Rutgers game where Edsall spent most of the second half on our own 1 yard line was pretty infuriating.
Notre Dame would have been up there if we had lost that one. UConn was absolutely dominating the line of scrimmage in the second half but somehow ended up in OT.
The entire 2009 season was frustrating. That was UConn's best team ever, and we kept coughing it up against inferior opponents. Cincinnati was the only opponent that year where I felt UConn was the inferior team.
2003 NC State was a heartbreaker.
Any loss to Greg Robinson deserves mention, especially when a made UConn FG is called a miss.
The 1 point loss to Virginia was something out of an after school special it was so ridiculous. DJ fumbles going in, then, on the final drive, UConn is within 10 yards of FG range and fumbles 2 snaps. BTW, if UConn won that game, it would have played in a BCS bowl because Illinois would not have been eligible.
2005 Louisville was frustrating in the sense that it felt like 15 degrees in the stadium but Hernandez was doing just enough to make me think he might pull it out, so I got to witness the fumble late and realize that no, he wasn't going to pull it out.
