Agreed - that's why I thought he would be better off staying in college for another year.
I kind of looked at it as stay in college get NIL in the mid-6 figure range and play 30+ minutes every game and likely get drafted higher next year then get mid-7 figures/year on a guaranteed contract or go to the NBA get low 7-figures maybe guaranteed and almost never play. Yes, he's financially better off in one year, but in three years he's way behind.
Look at what Keegan Murray, Jaden Ivey & Johnny Davis did by staying an extra year.
