Nuggets came back from 3-1 already and we know they do not quit but this is Lakers, they do not choke, specially not Lebron. If Lebron has to figure out a way to win the whole game by himself without help from his teammates, dude will do that. This dude played with a fractured hand and had 50+ point triple double against a warriors with Klay, curry, Durant, Draymond and everyone else, he would have won as well if JR didn't forgot that they weren't ahead, that idiot caused them the game.
I agree, but I don't think that Lebron will take everything in his hands with the Lakers, he has Davis now and one of the best supporting casts that can play offense and also play hard defense.
So, long story short I would have to say that 3-1 may not be guaranteed win for any other team, but on a team Lebron plays, when you are 3-1 ahead, it is nearly impossible for you to lose it from there, Nuggets are gone after this, maybe they will get one more game, who knows maybe even get another, but the last game of this series will be a Lakers win.
Lebron wouldn't let this lead go away like the choking Clippers. He has a lot of experience under him and players like Rondo who has also championship experience will be the key in game 4 close out.
