If I had to make a projection today, my most likely national title contenders would be this (listed in alphabetical order)
Arizona
Duke
Florida
Houston
Michigan
Next tier, I'd put at Final Four ceiling (also alpha order):
Alabama/Arkansas (one, but not both)
Illinois
Gonzaga
Iowa State
Michigan State
Purdue
St. John’s
UConn
Virginia
(If Tech still had Toppin, I’d include in this group).
Not much "hot take" in any of that.
There are maybe half-dozen teams beyond those I could see as out-of-left field Final Four, if there's a region with a little extra chaos.
