I'm late to this thread, but wanted to give my thoughts on some of the things you've all said.
I'm not sure what you mean by JUCO recruiting being faux pas? There's nothing embarrassing about it despite its outdated and inaccurate stigma--one of which is being challenged heavily with each passing year. Oats and several other current coaches have proven that there are ton of talented, high-character kids in these ranks that either a) needed a year or two to develop more, b) were severely under-recruited, or c) didn't quite have the grades in their first recruitment.
Power 5 teams aren't going to care as long as you win and don't have players getting arrested or things like the Louisville sex scandal of 2015. Texas Tech is the leading example right now of a Power 5 team infusing top JUCO talent and having success with it. They have one of the best defenses in the nation this year and are in good shape for the future.
I think it's fair to say there will be a slight drop off, but it's not as big as we all might initially think. The JUCO guys that are coming in really fit the mold of the last two years of the Oats tenure; Durey Caldwell is going to draw a ton of Jeremy Harris comparisons and Andre Allen is the newest installment in the Kadiri/McRae/Fagan saga. James Rojas is looking like to be an absolute steal of a recruit.
Add in the senior transfers, who are flying completely under the radar, as well as the current freshmen and Jordan, and I think we'll be in really great shape. Jordan coming back is going to be huge not only for next year's record, but for Segu's development.
Oats' resume already warrants a 1-1.2 million a year salary and that's going to be extremely tough for UB to do. Their best bet is to extend him with as close of a number as they can get to that. If UB can get it up to 750k and raises for the assistants, the chances of retaining him are much higher--especially if his contract is loaded with incentives like in years previous.
As for the standalone practice facility. I've heard through the grapevine that UB is much closer to the building a student rec center than we think. Oats may already be in the know of what's coming down the pipe, which in return should increase odds of retaining him. UB is definitely trying and they're in much better shape to approach this sort of conversation than five years ago.
Thankfully, Oats seems incredibly understanding of the university's situation in terms of facilities. I don't think quality of the facility is a pressing matter....yet. If the triple gym was SAs only; it would be a huge benefit for both basketball teams when it comes to their development. Having to work around the rec schedules is a tough task when you've got 30ish different athletes on different class schedules.
