Luka Doncic dropped 50+ points against the Bulls all by himself for the first time. with 51 points and 10 rebounds, he basically said i am the superstar of this team

But there’s one thing I really don’t get about him.
Why don't you play defense? You’re a young guy you’ve shown you can come up with steals when you actually want to. Why not be more agile? When you give your maximum, you’re the kind of player who can lead a team to a championship and you are the one that can finish the games in a single quarter...
Maybe what we are seeing now is his "MAXIMUM" already, and let's accept the fact that he isn't that reliable on defense.
That's his problem even since he's still on Dallas. Dude's not that reliable on defense that's why the management back them get some good defensive players like PJ Washington, Daniel Gafford, Lively II, etc. Well that roster worked for at least a season and they've reached the NBA Finals with that roster - something that I didn't expect. Now with LA, the team is at the bottom when it comes to defense, and part of it is because of Luka, and Lebron as well. Also add the fact that the team doesn't have any defense-first players aside from Marcus Smart. Luka's lack of defense is being covered by stepping up on offense hence, the scoring barrage that he did last game.
There are 2 things that the Lakers need to do if they want to build around Luka. They need to accept the fact that he's not that good on defense, and they need to build a roster around him where some of them are good or at least better at defense. What we might be seeing on Luka right now is his MAXIMUM so let's just accept the reality that he's not a good defender, shall we?

On point. He’s not good at defense, that’s it. Not everyone can play defense, and not everyone can play offense. Let’s accept the fact that not everyone can be like Wemby or Kawhi, who are good on both offense and defense. That’s probably all Luka can offer when it comes to defense, and it may not improve much anymore in that area. He’s more of a purely offensive player. It’s not that he doesn’t want to play defense, it’s just that’s all he can offer.
He did try his best to play defense even when he was with the Mavs. But probably since he is European, or that in his mindset, he is more of a offensive player. So it's just a matter of time that Luka will have that kind of numbers and for me, it could be too late to score that huge. But in any case, it's a big 50 points performance. He is sure the superstar of the team and he should be the one carrying them in the playoff since Lebron is somewhat on and off. But it's just a question on can he carry the team with himself like what he did with the Mavs. Reaves and others should really compliment Luka entering crunch time.
