While I largely agree with your point, there’s an alternate history where Young goes somewhere other than GT because Hewitt didn’t promise to focus on developing his basket-facing game. There’s really no way to know how much of Hewitt’s later stage recruiting success was due to his willingness to focus on preparation for the next level. It is possible that he could have been a more successful coach by “settling” for other recruits, but who knows.
I think someone, maybe MtnWasp, has argued that there was a middle way where Young played the 3 for parts of the game, but when needed shifted to the 4. Again, subject to successful recruitment and other sliding doors moments.
