Well FWIW, I had a close friend who has had collegiate AA's, and guys in the NBA, and is an assistant college coach assess Underwood's defensive scheme when he arrived.
I asked him if it would work in the BT at this level and he said no way.
It was same D he had used at SFA with success, and OKST with not very much success where they were 155th in country.
To his credit he changed it and he had what was arguably his best team (IMO) and best coaching job with the Feliz group.
Dunno about the tearing down to the studs metaphor, but we have a program that looks like it is sustainable at a competitive level now and he is figuring things out and seems to have a decent staff.
We need to take the next step and get to a S16 this year.
If we get upset in first weekend that will be a disappointment.
