Yes, people are very good at remembering only snippets of specific teams, usually biased by the team's postseason results.
A few notable games from the 1999/2000 team:
- Losing at Drake in the second game of the season
- Winning at Nebraska by just 1 (Nebraska finished the season 11-19)
- Winning against Texas A&M at home by just 7 (A&M finished the season 8-20)
- Losing at Colorado by 12 (to be fair, playing at elevation is tough, but Colorado also wasn't an NCAA tournament team)
- Winning at Texas Tech by just 8 (Texas Tech finished the season 12-16, 3-13 in the Big 12)
None of this is to say that the 99/00 team wasn't great; just that they had games where they underperformed and weren't dominant, similar to this team and every team, no matter how good.
