Those two were not ready for the NBA and knew it. Ollie has said as much in interviews but they made their own decisions. Hamilton didn't like college and deandre knew he was reaching his ceiling in terms of draft potential coming off the championship run.
They had limitations that will always keep them out of the league. Both were not athletic enough for the league. Both were in the bottom few in terms of vertical and lane ability in the combine.
I repeat: the vast majority of high level NBA prospects do not stay 4 years. IF Jalen is ready after this year, if the feedback from scouts says he could go in the lottery, he would be stupid not to declare for the draft.
I am unclear what is so shocking and insulting about this statement. It's pretty obvious to me.
