Indeed, Luka is one of the top players right NOW, probably up there with Giannis .......... he keeps this up, he'll be in the running with Giannis, Lebron for the MVP award.
He has range, has great handles, he's an elite passer, he's an above average rebounder for his position plus he has elite overall basketball IQ, similar to Lebron ............ making the right reads and right plays.
However, not to dampen Luka's story ............ methinks, this is about more or less his ceiling - he's basically doing everything at an elite level now, so it's not a knock on him.
One thing though, Luka is not an elite athlete - he won't likely be doing those putback slams, chase-down blocks that others like Lebron, Giannis, etc regularly do.
Luka's ceiling is probably Larry Bird - he has all the same traits as the great Bird.
