So you want him to lose out on a year of earnings? He isnt that good. He would have likely been in the same position if he stayed. Maybe he gets better and would become a first round pick, but maybe he doesnt.
He's a young athletic PG without a ton of skill. He was smart to get out early as possible and start earning.
And 300K in a year puts you in what, the top 5% of yearly earnings in America? That's life changing for a lot of people.
delayed gratification/bigger picture dude. he would've definitely been drafted with a better year and more usage at arizona. he's in a field that he can't work in until he's 65 like most regular jobs. was stupid of him to come out early, pure and simple. that 300k (and i don't think it's even that much) is over 2 years (and pre-tax) and he doesn't have anything guaranteed beyond that. post-tax he maybe got 200 of that; it's temporarily life changing but i doubt he has saved or invested much of that given that he bought his mom a rover as I noted. shortsighted as f*ck.
