I was rewatching the 1983 Finals before this draft. One thing in particular stood out about defending Moses in that series and that was that Kareem did do a good job on Moses.
Moses did a lot of his damage in the paint when Kareem was not defending him. Moses did most of his damage offensively against Rambis and Landsberger. These players were smaller than Moses. They were 6-8/6-9 and probably 230lbs. They simply do not have the size necessary to defend Moses and Moses chewed them up and spit them out.
I thought Kareem was outplaying Moses when they were head-to-head early in the series (Moses out-rebounded KAJ but KAJ outplayed Moses offensively & defensively) but that changed by game 4 when Moses outplayed Kareem.
--------
The Lakers had injury problems in those Finals. James Worthy did not play. He was hurt. Bob McAdoo played 2 of 4 games and when he did play he was limited. So the Lakers were without 2 of their 6 guys in the series. That hurt their depth which Philly exploited. They had some guys playing in those Finals games that I never remember playing for the Lakers. That is how far down their depth chart they were.
It also put more pressure on Kareem to do more offensively for the team so Riley tried to save Kareem on defense by putting Rambis & Landsberger on Moses instead. Which wrecked their defense.
It would've been nice to have seen a healthy Lakers team play in those Finals. Those games were already close (despite LAL losing each game). That series would've been much tougher if LAL had of been healthy.

Two other points:
(1) I am not sure about Moses destroying Gobert. Both Parish and Kareem should be decent markers for how Gobert might fare defensively against Moses. Moses will have some joy there, sure. But you can live with that. You are making Moses work and you gain more defensively by letting him attack Gobert one-on-one than you concede defensively by double teaming him. Gobert allows you to play Moses 1-on-1 and live with the consequences.
That is good enough. Especially in a league like this where you are playing the best of the best. You are going to have multiple guys who can score well one-on-one. You just want to stop those guys from feasting (which I believe Gobert can do) or creating wide open shots for others (which again, I believe Gobert can do).
(2) Dodgier ground for Draymond Green. Draymond's defense on centers is over-rated. He plays against mostly limited to solid offensive centers. Most of these guys do not have the skills or physical talent necessary to exploit Draymond effectively. This is not the case with Moses Malone.
Draymond does concede advantages to centers in the post. It is just that most post players are not skilled enough or smart enough to recognize those opportunities. I know that drove me insane watching Aldridge attack Draymond years ago. He just couldn't understand how to attack - where the opportunities were. And then you have guys like Marc Gasol who are not physically gifted enough and have a mechanical one-on-one game. This is not Moses Malone. Neither of these guys.
Guys like Moses Malone who are undersized centers and are used to outplaying bigger longer centers by having to use an added focus on quickness and versatility of moves ... these guys, when they get a little guy on them. Man, it's like Christmas for them. They destroy smaller guys on switches. That is what they do and what Moses in particular did.
Moses Malone is one of the most versatile low post scorers in NBA History. He has loads of moves. He can beat you in so many different ways. His skill-level is under-respected.
I don't think Draymond can guard Moses for anything more than a few seconds at a time. So a switch late in the shot clock - yeah, that's fine. More regular switching would leave Draymond exposed. And any switching of those perimeter guys onto Moses would be death for that defense.
Thoughts on their 1981 matchup? I've watched a game or two from that series and while Moses dwarfed Kareem in the box score, I felt that Kareem did a lot of things better than Malone that weren't captured by the box score (eg. passes that led to assists or power plays for his teammates, the quality of his passes/assists, rim protection, defensive rotations, etc).
And yeah I brought up Green as a guy who can switch onto Moses for a few seconds at the end of a possession when the defence is scrambling rather than guarding him straight up for an entire possession - Roy was talking about switches and I feel that Green can absolutely do that. Also not going to switch any of my perimeter players onto Moses lol, it'll be an immediate scram for Draymond or Gobert to pick Moses up if a mismatch somehow happens.
