In an entirely different NCAA period where there were fewer teams and thus games to play (thus allowing for fewer surprises) and with very restricted geographic comstraints, UCLA under Wooden had to wait 13 seasons before getting to a Final Four. They did not win the tournament that year, Cincinnati did. UCLA did reasonably well after that initial appearance. The tournament is harder to win as there are more games and no geographic constraints. Luck is also more of a factor in the tournament than in the past.
As for UK, that fanbase is irrational. I place them up there with Texas football fans as having unrealistic expectations. I do find your commentary curious, given the general disdain applied to them by this site. Aren't they recognized cheaters? (Death penalty anyone?) Aren't they cowards in their scheduling? I seem to recall reading that here. So now they are the fanbase that is a good line for comparison? That seems to be an odd suggestion given this site's posting history.
You seem to believe with certainty that something that has not happened before cannot happen. History in general and sports history in particular is replete with examples that deny that maxim. TCU won a national championship in 1938 and played for one Monday, albeit unsuccessfully. Your post suggests that they should not have gotten that far. By the way, Texas, a premier HS football state, had never had a team in the championship game until this week. UVa was nationally known in the Ralph Sampson era (early 1980s), but it took a very lucky game to get to the Final Four and then win it- more than 35 years. UConn had 13 seasons with Calhoun before they got to a Final Four. I guess that they should have fired him before that following your rule. The UConn team that won with Kemba Walker was among the last entrants to the field, only got in because they won the BE Tournament as a low seed and got hot. They clearly were not the best team but were lucky champions.
Again, writing about the future with certainty is ignorant or foolish or both. You have done that.
