I don't disagree with anything that you have said, and, college basketball is about to get A LOT more difficult with respect to recruiting if the new transfer proposal and NIL proposal are both approved.
My only issue with the Purdue model is that it is too difficult to have the class balance issues that it has had and have genuine sustained success, never mind elite success.
A stellar class of Hummel, Johnson, Martin and Moore...and then some classes in between that never rounded it out or added to it...great success with them...back to last place in the conference after them...then a stellar class with Edwards, Haas, Mathias and Thompson (that he was able to add to in subsequent years and was on the verge of great success because of it), but, those two guys that were the difference makers both left early and a 10th place finish in the conference followed...a really nice class coming in with the redshirts included...but, what happens while it is there to prevent a 10th place or last place finish when it moves on?
Purdue had a 4-man class with those first two that it had to replace ultimately, and, it now has a 5-man class that it will have to do the same with...it was already difficult as we agreed to do that...it is going to be more difficult...either way, it is not a good model for a program like Purdue in my mind.
Off-topic relative to this specific matter, but, it does not look good either for a developmental program when two guys that contributed from Day one leave the program just before their final year in it...their lack of development says more about them than Purdue to me admittedly, but, it does not look good regardless...and, it is bad optics to have guys like that bail on the program...again, says a lot about them, but, it is concerning for Purdue's/Painter's sake as well...not a lot of programs that see guys that were contributors to the extent either of those guys were and in captain/leadership roles bail before their final year...that said, given where the one ended up and the other is likely to, that again says a lot about each of them as individuals.
