I hated his game because I thought it involved over dribbling, blackhole ball dominating, and foul baiting, but Houston Rockets James Harden was about as unstoppable and unguardable an offensive force the league has ever seen, particularly for a perimeter player. And sure, a lot of it had to do with forcing foul calls by initiating contact and flopping. But it was gaming the system and it worked. His ability to get to the rim to force a foul call combined with his side step three made him an even tougher guard than LeBron imo.
And again, I hate to say it because I despised watching his game.
But I actually view Luka similarly in his variety of offensive skills, ability to use both strength and finesse/skill, and ability to attack whatever kind of defender or defense is played on him. The one thing I hope with Luka is that he finds a better balance with his ball dominating isolation approach on offense and him being being able to trust his teammates and becoming more effective playing off the ball. Harden never evolved his game that way. And I don't mean Luka simply being able to let other guys like Brunson and Dinwiddie take over while he stands and watches from the weakside elbow. I mean Luka actually playing off the ball, setting screens, then cutting and slashing, forcing defenses to chase him even without the ball, running the wings on a break where he's the finisher and not the guy leading the break, posting, kicking back out, then reposting, forcing the defense to work a little bit more.
I agree that Luka is already one of the most unguardable scorers ever. I think he can be even better.
