To add to point 3 he could definitely take lessons from TP and Manu if he wants to further improve in that category. Manu has truly made the "euro-step" famous here, and now its being used all the time by other elite wing players. D-Wade has really mastered it and you even see Kobe, Harden, and sometimes even Durant using it to avoid charging fouls. I actually saw a bit of that from Kawhi during his brief summer league stint this year. Could you imagine how nasty Kawhi could be if he can incorporate TP's floater into his game? With Rondo esque arms/hands its very conceivable that he could improve the way Rondo has with his intermediate finishing.
That would actually further complement his apparently flourishing mid range game. Paired with his ability to spot up from range, it could truly be something special. If somebody tries to aggressively close-out on his 3 point attempt he can blow by and hit mid range or take it all the way to the rack.
I think the most impressive aspect was the fact that he got a lot of buckets off isolation or via the pick and roll. As teams stat to respect his ability to score off the dribble its up to him to develop as a passer to essentially be the Manu/Harden of the team... but paired with amazing defensive ability.
