I don't know where you get the IT comparison like he is version 2.0 but even if he is he as an 18-year old is 8 inches taller which already gives him an edge.
I am hearing he could be a "James Harden" 2.0 or Russell Westbrook 2.0 which is even a step above.
I didn't realize Fultz grew to over 6'6 overnight.
I didn’t know IT was 5’10’’
At the 2011 NBA Draft Combine, Isaiah was measured: 5' 8.75" w/o shoes, 5' 10.25" w/shoes.
At a workout for the Nets the same year, he was measured 5' 9" w/o shoes, 5' 10.5" w/shoes.
At the Deron Williams Camp that year he was measure 5' 11" w/shoes.
Seems pretty clear he's at least 5' 10" w/shoes.
Fultz' tallest measurement to date (2016 Nike Hoop Summit) had him at 6' 4.75" w/shoes.
On the larger topic of this thread:
I do see tremendous similarities between Fultz and Isaiah. But the most important similarity is they both have the ability to be elite scoring weapons both on or off the ball. Thus I see them as potentially a fantastic complementary pair that would be incredibly difficult to defend.
In Stevens' nomenclature, there is no 'PG' or 'SG'. There are ball handlers and wings. Both Thomas and Fultz can move smoothly between either role, probably often on the same play.
