For me it would either be the 1997 loss vs WVU or the 2010 WVU loss. Just personal reasons. Both games were ours to win. Also think back to that 1997 game and just how many NFL players were out on that field for either team.
Here are some of the other losses that would be nice to have back.
1987 loss to ULM for the I-AA National Championship
1991 loss to Youngstown St for the I-AA National Championship
1993 loss to NCST (We were robbed)
1993 loss to Youngstown St for the I-AA National Championship
1994 loss to Boise St in the I-AA Semi-finals
1995 loss to Montana for the I-AA National Championship
1997 loss to Ole Miss in the Motor City Bowl
1998 loss to Bowling Green that prevented an undefeated season
2000 loss to Michigan St (only lost by 10. 24-34)

2006 loss to UCF (we lost 22-23 with McG and McConaughey on the sidelines)
2007 loss to New Hampshire (this was just plain embarrassing)
2012 loss to ECU in double OT
2013 loss to VT in triple OT
2013 loss to MTSU (lost 49-51 on that last drive)

2014 loss to WKU that ended a perfect season
2015 loss to MTSU in triple OT

2019 loss to UCF
