What if?
This will actually be the recipe for another Nuggets championship. Luka with Jokic, and Murray as the shooter, without MPJ in the roster anymore. It's actually a strong roster with the 3 stars healthy.
The NBA type of game doesn't play defense anymore, so yes, they could get a ring with that. The Nuggets played 7 games in the playoffs against the OKC. That means a lot, and adding Luka will get them a big plus.
It would be absolutely fantastic to see Dončić and Jokić playing in the same team. They would be a big contender for the championship. But I don't see any reason for the Lakers to let Dončić go. I also don't think the Nuggets have enough pieces for doing such a trade. This rumor doesn't seem very realistic to me. Of course, anything can happen in the NBA. Considering how Luka left the Mavs, you can't rule anything out.
Luka didn't left the Mavs, it was Nico who decided to shift him out and we all know that it causes a lot of noises in the NBA. But I would agree that everything is possible now. Before there are only a few teams that can make a big 3.
But now, it's totally different, of course, there is the salary cap, but teams are smart enough to go and maneuver around it so that they won't go over. I think the Nuggets are still a good team even without MPJ. They already developed Braun to be their next MPJ that's why they are wiling to trade MPJ already.
