The culture of the Nuggets since their last playoff appearance had been a mess the past couple of seasons, mainly because of how inept Brian Shaw was as a head coach & the leader of your team/best offensive player being the most immature player on your roster.
As much as I don't like Iguodala, losing him for Foye was a pretty big drop off as well. And it's no secret about the various health issues since that playoff season too.
I really like the culture of the franchise since getting rid of Shaw/Lawson, though. Even though they're not winning. Gallinari is a hell of a team leader, and seems like he's getting more consistent offensively and doesn't shy away from big moments. Lots of great young pieces in their 20s like Mudiay, Jokic, Nurkic, Harris mixed with some vets like Chandler, Nelson, Augustine, Faried, Miller.
I think Malone is a good fit for this group, thankfully the Kings franchise is a mess and got rid of him.
The young guys have high ceilings and just need to continue to develop. If they can continue to do that, and the vets manage to stay healthy (which seems impossible), no reason this team can't make the playoffs in the next few years.
