On how long it lasts, your guess is as good as mine. Nobody really knows...
Obviously, conference realignment is a big factor on the budget topic. And budget is, of course, a very important part of the overall equation. Not more important than the ability to scout, evaluate, develop, and game plan though.
We need to spend at a certain threshold to be competitive for talent. But you get diminishing returns above that level of investment. Indiana spent probably 20M on this roster and they're thrilled it's considered top 40, lol. UK spent 22M last year for Pope to drive the clown car off a cliff. In a way, I think not spending like drunken sailors acts as a filter for those non-culture fits anyway.
Not saying that to diminish the importance of money because that's one of the top 2 factors for basically every talented player these days. I just don't see a catalyst for him to get frustrated enough to walk away any time soon. Granted, that could change after a few underachieving seasons. But I doubt we experience many of those now that the program is humming like a well-oiled machine. We shall see.
