I know TKR did not come to Purdue with the idea of being "willing to wait" for anything, and, I have no idea how it plays out obviously, but, my guess is that if he is playing 15 mpg or less, that, he may not be thrilled about that...who knows whether that is truly the case or what it would even mean if it were, but, I am confident that he did not come to Purdue with the idea of not getting meaningful minutes or being impactful until year 3 (and, even then, if Zach returns...and I believe that he will (assuming Purdue at some point between now and then does actually figure out NIL), it won't be year 3 potentially even).
My guess is that Furst won't love the idea of being a backup for 2 more years either.
Even if both were ok, Purdue is not better as a result...Purdue is not better with those guys sitting on the bench..to your point, they are indeed wasting talent.
I have no idea what Trey will do this year, but, I know that coming in and out of HS, he was a better player with a better skill set than either Mason or Caleb...those guys have both had some success...no reason to think that Trey will not, but, if he is only playing 15 mpg, and, doing so simply because he happens to play the same position...that j ust does not make sense...for him, or, for Purdue.
Again, if Morton is playing more simply because he is a more traditional 3 arguably, despite not being an actual better player...it does not make sense...and, while it is not Trey's best or most natural position, if it means getting him on the floor rather than sitting next to the HC on the bench...that does make sense.
