After winning the Finals this year, the nuggets are pretty much bringing back the same team without Bruce brown but other teams like the bucks, Celtics and suns have improved. Imo I think the next 2-3 championships will be won by either the Bucks or Celtics and I think the Nuggets will make the finals again this year but the only way they might win again in the future is to either make a trade for a 3rd star or get much better depth.
It’s hard to repeat because when you win, other teams actually see how good your role players are and they will pay more than you can pay to take those players. Nuggets already lost Bruce Brown. They might lost someone else next offseason.
