Hasn't it been that way for decades? 90% of final four teams come from the Big 6 conferences.
I think NIL and the portal have led to more competition.
There were 11, P6 teams with less than 10 losses. All had at least 6 and the average # of losses for the group was 7.4. 2 Made the Final 4.
Mountain West made the Elite 8 and Final Four for first time ever. People forget that these teams have all made the Final Four in the last 10 years.
San Diego State
FAU
Houston
Loyola-Chicago
Wichita State
In the end good coaching and building rosters is going to be key to winning, NIL and the portal can help. Every game can be found on TV from St. Thomas to Duke. So many factors including realignment/expansion of conferences all playing a role in parity. There are 300+ D1 teams and seeing a team in MN jump from D3 to D1 shows how slim the margin is.
St. Thomas played with Creighton. Merrimack made the jump to D1 and won their conference, while #2 FDU won two tournament games. NIL $$ in some of these college towns/areas is likely to compete with metro areas where there are professional teams.
My issue with NCAA basketball is officiating. Needing to cover that many games and styles of play lead to so many inconsistencies in games, officiating and quality. They should widen the lane and allow for 6 fouls. People don't come to watch the bigs sit on the bench with 2 fouls because the officiating is so inconsistent.
