A lot of it is orange colored nostalgia. Basketball was fun under Pearl but here he had a lot of the same problems Barnes had, his teams didn't show up in the postseason. His Elite 8 team was actually a surprise considering that SECT we got curb stomped by Kentucky. People don't seem to remember there was a TON of complaining about Pearl not winning in the postseason and wondering if he had peaked before he had the unexpected E8 run.
The funny thing about that 31-5 team that was maybe the best team ever at UT was people rememer that Memphis game but not how badly the season ended, and by people that don't seem to realize that a regular season game does't mean more than a Sweet 16 game.
