I'm skeptical of dook, but besides that it looks like a reasonable list. I wouldn't consider any of those B1G teams a "surprise", except maybe for Wisconsin (but only in the sense that Wisconsin typically underperforms in March).
By surprise, I mean that because the top B1G teams are so even they have pushed each other down to the 3 or 4 seed level. I expect on of them to get into the Final 4.
I expect Duke to get the 1 seed in the East (NYC) due to the fact of their annual good future with the NCAA selection committee. Thus, they will get to the Final 4 through Raleigh and then Final 4; but, would love to see them upset.
Arizona will be the 1 seed out West ; but, due to their perceived ‘weakness’ due to injury and the lack of depth in the PAC, I see them getting one or two of the afore mentioned B1G teams as a 2/3/4 seed.
In the north, Wichita will get the 1 seed in Indianapolis. That said, the NCAA loves Cinderella teams, which Wichita is not this year; but, needs to money teams in the Final 4. Thus, the Shockers reward for going undefeated will be to have Kansas as the 2 seed - a team that on any given day can win or lose to anyone.
Florida will be the 1 seed out of the South (Memphis). I don’t see anyone beating them except for some really well coached team, with bangers and locked-on Seniors (maybe Izzo’s State team). I can see Louisville as the 2 seed south; but, Florida is a deeper team and no way will the refs allow Harrell to bulldoze over players in the tourney as he did to UConn and others this season.
