He's athletic like James Harden, with similarly supreme hand-eye coordination. what you just posted is sort of like what people thought of Fultz when he was ranked in the 20's in HS not #1, those concerns are unfounded though. He's sorta like Jrue but a super rich mans version, Jrue was so much more raw offensively at this stage.
His 'saving grace' as a prospect if you will is the magic that goes on with the ball in his hands, I posted back when he was ranked lower in HS "This dude has the ball on a string". He doesn't have a blindingly quick 1st step but he's got a good one. The real magic is not his acceleration but its his ability to decelerate.. He's quite simply one of the best 6'4" guard you'll ever see at 'stopping on a dime', his ability to change speeds and directions is like water, if there's the slightest crack or seam in the defense he's gonna matriculate thru, and make it look almost effortless.. This is why there's Dwayne Wade comparisons(They're built similarly too)..
to me it's in the realm of amazing tho.. Fultz isn't just like very good, he's gonna be a gamechanger for some bad team... Like I said months back this years lottery is infact the "Markelle Fultz sweepstakes"
