A sweep is not impossible but I could see Lakers maybe getting a win there too, I am not entirely sure if Lakers even believes they could win, let alone others and I believe that Denver Nuggets are a team that would be hard to beat by anyone this season, with no injuries and Jokic playing like an MVP still, they are a great team and Lakers will need to win against them four times, which I think is not possible at all.
The Lakers on the other hand have a very deep bench. So whenever Jokic and Murray will rest for the Nuggets, they should take advantage of that because that's may be the only time they will have an upper hand against them.
An injury on one of the 4 Denver starters will be a huge problem. The Lakers are at the bottom of the rankings but they are a veteran team and they too are very dangerous especially when healthy.
Lakers has the bench but the good thing about Denver provided they are all healthy is they can make adjustments like always putting 2 of their main players on the court or at least not resting all of them for long. But it will be interesting to see how the Lakers can capitalize once Jokic is out of the court.
We can always consider that injury, but it could happen on either team. The Lakers are still the same team, I don't see them being a more superior than the Nuggets as even in the regular season, they can't beat the Nuggets on their home court. Maybe this will be no swept but I still see that the Nuggets will come out victorious in a 7 game series.
Who would stop Jokic? That's a big question, if they had Howard maybe it's possible, but aside from Davis,there's no other bigs on the Lakers that could minimize (at least) the production of Jokic.
