There must have always been parity if having non traditional teams in the final 4 or first time champions equals parity.Not sure what you're watching if you don't think this year had parity with top 10 teams having a losing record on the road against unranked teams. And it's not just parity, it's also traditional programs not being as dominant. Last year's Final Four was UConn, FAU, Miami, and SDSU. This year had Alabama get their first, NC State get their first in 41 years, and Purdue their first in 44 years.
UConn is doing UConn things, but the makeup of the last two Final Fours shows the landscape has changed. 2021 also had a first time champion and the Final Four was three non-traditional powers and a 11 seed UCLA. 2019 was two first time title game participants, a first time Final Four Auburn, and Michigan St.
If you can't clearly see the landscape changing then I dont know what to tell you. Acknowledging the changing landscape isn't a defense of Cal, it's just reality.
1939: Oregon ( first and only final 4 for the next 74 years)
1940: Duquesne (only final 4). USC (one of only 2 final 4s in school history).
1941: Pittsburgh (only final 4). Washington St. (only time they have made it past the Sweet 16)
1942: Stanford (only final 4 for next 56 years).
Dartmouth and Colorado (one of only 2 final 4s in each of their history)
I don’t have time to do this for every season but it happens a lot. Fast forward to the Pitino era.
1990: UNLV(only title in their history). Georgia Tech (first final 4 in their history)
1991: Duke (first title ever)
1992: Cincinnati (only final 4 in the last 60 years)
1994: Florida (first final 4 in school history)
1995: Oklahoma State (first final 4 in 44 years)
1996: UMass (only final 4 in school history) Mississippi State (only final 4 in school history)

By the time the 2025 tournament rolls around, it will have been 10 years since UK has been to a final 4. No coach in the history of the NCAA tournament has went 10 years at UK without a final 4. Now before you say UK never won a championship before 1948, you have to realize that the NCAA tournament didn’t become a thing till 1939. So yeah it’s a fact, no coach in the history of the NCAA tournament has went 10 years at UK without a final 4. Ask yourself when was the last time UNC, Duke, or Kansas went 10 years without a final 4?
