I just looked in to this - there's nothing about him from anywhere reputable on the web about him as a prospect, and he played 3mpg in EYBL. There's some info out there from JBA (Ball league) affiliated links suggesting he was a 4* prospect, had Div 1 offers, but there's nothing to verify that, and there's even suggestions he has lied about his age.
Watching what footage there is of his game makes me think he'd struggle to make an impact at NBL1 level let alone getting minutes on an NBL team.
On top of this, he seems even more of a headache than the Ball dad, in an interview on YT he described himself as the best shooter in his class and he said "my agent said I'd be a star in Australia, they love me", lol.
So my initial reaction to all of that is that this guy can't seriously be considered for a Next Stars spot. But then, there is the connection to the Ball family, and LaMelo is obviously a legitimate candidate for a N.S. spot. It seems quite unusual for Ray to just put this out there so definitively if it's clearly not true.
So maybe there's some sort of 'package deal' with LaMelo at play? Idek.
One thing that appears certain to me is that if he was put on an NBL roster, he wouldn't be getting many, if any, minutes, so it should be inconsequential regardless. LaMelo himself, who actually could be a lottery selection if all the baggage and BS wasn't attatched, will only be getting a backup role here in the league, and we've seen guys with legitimate draft buzz in Bowen/Ferguson be rotation pieces at best. A guy with no serious draft chances isn't getting minutes.
I just put a tweet out to Uluc/Santamaria/Ward about it, we'll see if they debunk it.
