I know this is a lot to digest but wanted to provide the info and explain the best i can.. In my previous post I back tested 5 years.
@exploited17 asked about prior seasons beyond that so I went back 10 seasons, excluding the covid season in 2020 as the tourney was canceled. This is what my research shows.
8 of the last 10 NCAA touraments have been won by a #1 seed AND who were in the top 6 in pre-season AP poll, pre-season BPI & pre-tourney AP poll.
The 2 outliers were 2014 Uconn & 2016 Villanova. In 2014 Uconn defeated Kentucky, a pre-season qualifier only and in 2016 Villanova defeated N. Carolina who was a full qualifier in all criteria. Pre-season and pre-tourney rank & tourney seed.
Below is all the info I've researched, including the qualifiers for this season. Houston and Kansas the 2 qualifying teams with just HOUSTON remaining. I also have Gonzaga listed only because they were a pre-season qualifier but did not qualify with their tourney seed and pre-tourney rank.
