Not every great player has a play you remember but this ain't THAT far off.
Iverson - the cross and jumper on Lue, stepping over him
Shaq/Kobe - that alley against POR
Jordan - the shots on Russell, Ehlo
Dr. J - the dunk on Cooper, the reverse layup from the other side of the basket, dunk on Kareem, dunk on Walton
Magic - Junior, junior skyhook
Isiah - that corner jump shot on the sprained ankle against the Lakers
LeBron - game-winner against the Magic
etc., etc., etc.
Even roleplayers:
Horry - the 3 against the Kings
Fisher - .4
Kerr - the 3 against the Jazz
I really can't think of one for Duncan; that jumper he hit against Shaq before Fish hit the .4 stands out, but Fish hitting the shot kinda ruins that. Maybe the wide open 3 he hit to beat the Suns that one year.
