Oh so he's born somewhere between '98 and '00.. interesting.. You think he's got lottery/Exum level talent huh?? Why doesn't he play for Lithuania's youth teams? (or am I mistaken about that?)
I've posted about Doumboya and Jankovic before, they've both easily got NBA talent.
Doumboya just started playing basketball in 2013 and is easily one of the best NBA wing prospects in all of Europe, he's going to be a monstrous defensive prospect like you described about the Lithuanian...
He's kinda like Simi ****tu.. Also he's born on 12/23/2000 so he's likely to be the youngest player in the draft if he declares in 2019.. Will likely be a teammate of Rudy's on the French National team.. He's from Guinea though.
Jankovic is a much better version of Kyle Anderson, and he's already 6'8", phenomenal Point forward type of feel for the game.
