They have the same flaws as players, tbh, the difference being that George has had the luxury of improving his game as a top option on his team, while Pop admitted he doesn't even run plays for Leonard..
I've been saying all year that casual fans stupidly believe that Kawhi is a product of the Spurs system, when in reality, the system hinders his offense..he's not a great spot-up shooter, but that's the role he was forced to play most of the year when he's on the floor with Parker, tbh..
George has improved his ball-handling immensely, while it's still a flaw for Leonard..George is also a very good passer, which isn't a strength for Leonard..OTOH, despite being smaller, Kawhi's post game is already more advanced than George's..as somebody else already said, George seems to have soft tendencies, too, while Leonard has already shown that he doesn't back down from anybody, tbh..
George has a slightly higher ceiling IMO, but it's close..Leonard has the advantage of learning under Duncan, Manu and Parker, too, tbh..
