While I don't love it, to call it indefensible or idiotic is silly. We really don't have much insight into how good a coach Hubert is or isn't. He is a long-time assistant, similar to Mike Hopkins who was coach-in-waiting for Syracuse for awhile (yes I know how UW has gone for him). He also has NBA experience, a big plus, and established recruiting relationships as he's led on a number of our guys. Objectively, I don't think it's at all clear that Wes should be given the nod over him.
Assuming it was possible, I certainly would've gone for Beard/Drew/Oats/Holtmann over Hubert. However, this is a case of unknown-unknowns as a fan. I just simply have no idea how good a coach Hubert is. Roy and Bubba at least have a better idea. If they feel strongly then that is a good indicator on its own, for how little other data we have. I'm definitely excited to see how next year looks now!
I've mentioned on other threads, but there's also some nice optionality in that if Hubert doesn't work out we can easily give Wes the job in 3-5 years, in which time hopefully he's gotten successful power conference experience. This will likely always be the top potential job for Wes, so we have very little chance of missing out on him by waiting IMO.
