That is very hard to answer, since Purdue is arguably the only Power-5 basketball program (IMO) that refuses to go full-bore NIL (so far).
There are 3 scenarios...
1. Continue to do it the old-fashioned way with recruiting, because so far it has worked. This is where CMP is at and does not figure he needs to go NIL, over a recruited kid(s).
2. Join the NIL way of doing things because the recruiting method is no longer working, and conference foes are surging ahead of you.
3. See the NIL writing on the wall and retire from coaching because of it (Jay Wright). Which, BTW, would require Purdue to go ahead with a national coaching search and hire a proven coach and not a "lets hire this assistant and see what happens".
*All of the above assumes that the NCAA does not develop and enforce a NIL salary cap, so team A with alumni/boosters cant outspend team B that has alumni, but not as many boosters.
