a) How does Bob not remember that Ell played the entire game against OSU?
b) I'd use tiers of meaning for the games with less hurt as you go down the tiers.
Losing twice (12 BU, 98 aTm) on the cusp of a NC appearance. 98 will always be the worst b/c we also lost a conference title.
Losing the other Big 12 title game. (00 OU)
Losing huge regular season games when you know your team is a legit contender. (00 OU, 02 UT and CU, 03 UT and OSU)
Losing to lower level teams (Fresno, Marshall, NDSU).
Loses that make you realize your team is good, but not THAT good. (96 NU, 97 NU, 99 NU, 11 OU, 14 TCU)
Big bowl losses (96 BYU, 03 tOSU, 11 Ark, 12 Oregon)
Other notables IMHO. (93 ISU, 95 CU, 01 OU and CU, 04 and 06 KU, 10 NU, 11 OSU, 13 OSU and BU)
