I would just add that building a team at a small mid-major school, you don't really have the talent to compete with most of the teams you mentioned above. It's more about building consistency, winning your conference, and making the occasional tourney run. He's done that, and the level of players he will be able to attract at a big12 school is wildly different than he's had in the past.
There are never guarantees when you hire a coach. Sometimes what seems like a slam-dunk turns into a nightmare. Sometimes a ho-hum hire turns into a jackpot.
He will have to deal with new challenges at oSu. Higher expectations, a big donor who wants to call the shots, and much, much tougher competition in a tough conference.
He will also likely have some advantages. oSu is a better squad than they showed this year. If Forte comes back, he and Evans will be a tough duo to stop. They have some good talent there, and if they just finish middle of the pack, it will be considered a great improvement over this year. I think just about any coach could take the talent they have and finish in the middle of the big12 next year, so he gets a bit of a head start. With that, he will likely have some goodwill that carries him a few years as he builds.
In all, though, I think it's a pretty solid hire. Not super flashy, but not that risky either. They need a grinder who is ready to put in a lot of work. Not just on the practice court either. They have to rebuild the fan base, and rebuild the relationship with boosters as well. They need a "community" type of guy who is everywhere all the time selling the program and creating excitement.
