I live in the Midwest and don't get to see Jaylen play as much as i would like but from what I have seen he definitely has All Star potential. His defense is very good and with his athletic abilities he has the potential to be a star!
For me, the question is not really if he has All Star potential but more if he has All Time potential? The guy is not that far from being a dominant player right now. His offense needs to improve some but he most definitely has the tools. Someone once said that 'you can't teach height', well, you can't teach a 40 inch vertical either.
I really do think he has the potential to be an All Time great but time will tell.
