Paul George gets a ton of leeway with Indiana, he doesn't play championship ball, he doesn't follow a system. He can put up whatever he wants because in the end it doesn't matter, nobody gets up to even play his team. He played on one of the youngest, most athletic teams in the league, and that it's self is a system that a player like Leonard has never had.
Both Butler and George are products of the East. During George's "superstar" year he needed 7 games to get out of 1st against a 38 win Hawks team, and 6 against a 42 win Wizards team. Just last year Butler needed 6 games to get out the 1st against a 41 win Bucks team, I can imagine the flack a player like Leonard would be getting struggling to beat these teams lol.
