Denver has the highest FG% in the paint with Jokic on the floor.
His passing literally creates more open looks than anyone else in the entire league.
He literally transforms what would be one of the worst offensive support casts into being one of the best-performing ones. There's nothing "severely underrated" about the likes of Milsap, Grant, Harris, Morris and Craig, who while bring their own offensive strings to the team's bow, would otherwise be condemned if it wasn't for Jokic setting the table for them. All of Murray's 40/50-point games, and the support cast making timely shots, have Jokic's fingerprints all over them. Murray and the role players can almost exclusively focus on scoring, and not have to worry about facilitating for one another, making sure they all get regular and equal touches, on top of generating open looks for one another. Their chemistry exists because Jokic is the nucleus. That same magic isn't happening with AD in place of him.
It's not too dissimilar to the offensive success the Warriors have had with Steph, with the way he generates open looks for his team (with the gravity he has by teleporting all over the floor) and the selflessness he has by sharing the ball. You can't just drop Dame into that system and expect the same magic to happen. Dame and AD are buckets, but they don't play in a manner that elevates those around them. They'll get their points, but it can be in the run of sacrificing the betterment of the team.
This can not be emphasized more.
