What single aspect of Zion's game should he focus on in the offseason?

Assume that none of our current players get traded, Murray comes back midseason at ~90% of what he was pre-injury, and Herb/Trey are fine. That's a somewhat optimistic outlook, but we'll make up for it by ignoring whichever talent draft pick that we add.

Also assume that Zion starts off the 2025/26 season in similar shape to what he's at now (I really think that this will happen). So if you can force him (potentially at gunpoint) to spend an insane amount of the offseason improving in the area of your choice, what would that involve? Again, ONE area (not "work on each of x, y, and z").

Free throws are an obvious issue, and working on this would likely improve his midrange/deep shooting.

Zion adding a ~36% three point shot would be impressive, and help open things up for the offense. That's especially the case if he can shoot a good percentage on pull-up shots while running the offense. Focusing on midrange shots may be a better idea than the 3's. Either way, given the way that he commands the offense, he probably shouldn't waste time practicing catch-and-shoot efficiency. Even if he's camping out in the corner or elbow and takes in a pass while wide open, he's going to look to drive. If the defender gives him space and dares him to shoot, he's not going to do it until at least 2-3 seconds/dribbles after he gets the pass.

He's not a good rebounder, but I'm not sure how you improve that.

I'm too casual of a fan to really pick apart his defensive issues. To me, they seem mostly based on how engaged he is and how fat he is. You can't expect him to play Herb level defense given his responsibilities on the offensive end. But I've seen him (as well as Trey) play lengthy stretches of really good defense. They have the ability to do it. Maybe you gentlemen see some obvious areas to improve on.

Personally, I'd lean towards having our expert medical staff removing his left arm for a few months while he practices his handle, then re-attaching it shortly before training camp. Have someone like Derek Zoolander (an expert on going/turning right until he was absolutely forced to go left) work with Zion on his right-handed drives/handle. As titillating as Zion adding a jumper/3 is, he'd have to be pretty great at those shots for them to be worthwhile. He'll absolutely need to work on his shooting as he ages/slows down, but he looks about as spry as ever currently. And I know that I said working on his already elite skills have diminishing returns, but Zion becoming an ambi-driver (left or right) won't just help his short range game, but it opens up a lot of assist opportunities.
