College basketball is weird this year

In a given season, I think we generally expect three of a group of 6, Duke, North Carolina, Arizona, Michigan State, Kentucky and Kansas to be near the top of the heap and earn tournament 1 seeds, with a second tier, including Syracuse, Villanova, Connecticut, Memphis, Louisville, UCLA, Florida and Gonzaga occupying several of the higher seeded spots, with maybe one or two upstarts filling in a final 1 seed, or claiming a stray 2 or 3 seed. This year, looking at the top 12 teams in the country, there are several new faces. Looking at the AP poll, those schools are
2 - Virginia - an ACC team usually forgotten behind the rest of a formidable conference, though resurgent in recent years
3 - Purdue - Despite my high regard for them, this is the best Purdue team in decades.
4 - Oklahoma - OU can usually recruit, and has the best freshman in the country, for the first time since the days of Blake Griffin.
6 - West Virginia - Bob Huggins is still coaching, but doesn't seem to be getting in as much trouble as he used to. He might just be good at his job.
7 - Wichita State - They even switched conferences to raise their profile. Mission accomplished!
8 - Texas Tech - what
11 - Xavier - The A-10's finest, which is usually only good for being ranked 20th or so.
12 - Cincinnati - By these rankings, Cincinnati isn't even the best team... in Cincinnati! And yet, they are the 12th ranked team in the country.

That's 75% of the top 3 seeds that would go to teams that most people wouldn't describe as blue bloods. That's going to make for an interesting tournament this year. (But it will probably be Villanova vs Duke in the championship game.)
