Wall has Gary Payton level of potential, I doubt he reaches it though.
Kyrie doesn't have as much potential, but he's much more likely to reach his ceiling than Wall.
Kyrie's max is far beyond Gary Payton. By the time Kyrie is 24 (the age payton was when he finally put it all together) and has a solid team around him, you looking at something like 22-25ppg, 7-10 apg, and 4 boards...depending on what they need from him. he can give you that for the next 12 years...easy.
while y'all still talkin about wall fixin a BASIC JUMP SHOT, kyrie has added...
a post game, complete with a fade J
a lefty floater
a euro step, only surpassed by wade, harden and manu
a pull-up 12, 15, 18 and 20 footer
and he's improved his defense.
a player's "ceiling" is his projected maximum productivity based on his intrinsic skillsets and physical gifts.
some of you base ceilings ENTIRELY on physical gifts. and then you limit those physical gifts to speed, power and leaping ability. agility is thrown out the window. endurance? out the window. hand-eye coordination? don't even matter.
FWIW, agility and hand-eye is why kyrie finishes better than wall and every other jumpin jack. the ability the square up to the basket at odd angles and apply just the right amount of spin and touch on layups over big azz humans ain't something that can just be "DEVELOPED." like, "oh...i'll just practice that. it'll be fine" you either got it or you don't. wall ain't got that or a jump shot or elite change of direction handles.
next season, if john wall can do what jrue holiday is doing NOW, then this is a legit convo. jrue a 19 and 9 all-star.
as it stands, it's just some dudes who been waiting for their guy to get back and cysed off a 9-7 "hot streak" (led mostly by two 30 year-old bigs who tryna get traded, by the way...but give wall all the credit) by a team hellbent on playin themselves out of top 8 pick.
