It's likely he was tired, and that's perfectly understandable given he's been really putting the Cavs on his back in each of these three Finals. However, while he is different than MJ and Kobe, it's important to note that all three were incredible two way players. Furthermore, while being tired is an explanation for some of LeBron's 4th quarter struggles his mindset is also a key factor - sometimes he just tries to make the right play by passing to the open man, sometimes he tries to just get the ball out of his hand. But just to be clear, what I find interesting is the fact that LeBron has earned the reputation of not being clutch (and at times shrinking) yet we've seen him be extremely clutch and hit game winning shots, and that dichotomy is both intriguing and difficult to comprehend.
As for depth, I mean LeBron is playing alongside two All-Stars, one of which can get his shot anytime he wants. He has a decent collection of role players. Generally speaking most of them haven't shown up in the Finals, but this notion that the Cavs don't have depth is a scapegoat to me.
The Bulls and Lakers were pretty comparable, 2-3 perennial All-Stars, 2-3 really good role players, and 2-3 capable role players.
So I'm not really a Cavs fan, and I don't watch them play too much. And I'm not trying to give Lebron a scapegoat or anything. But your original posts was how in the 4th he's invisible. And to me, it seems like being tired and the Cavs roster is plays a huge part in it. Why is it that every game Lebron doesn't play Cavs lose? Why is it that when Lebron sits, usually the other team takes over? The only time I can think of it not happening was I think Game 4 of the Celtics Cavs series, where the Celtics failed to push their lead more when Lebron was out.
Cavs may have a great supporting cast when Lebron is on the floor, but it seems to me when he's off the floor the whole team falls apart. Because of this Lebron barely gets any rest, which lead to him disappearing in the 4th.
Would Bulls fall apart when Michael sat down for 5 minutes? Would Lakers if Kobe sat down? Because that's what I've seen from the Cavs. I feel like part of that blame goes to Lebron, I imagine he had a firm voice on who he wants and doesn't want on his team. But at the same time, I can't say Kevin Durant is a better player than Lebron (like others outside of GAF are doing) just because he had a better 4th quarter. Because Lebron has to do so much more on this team than other players have to do on their teams.
When did he choke?
I just like posting how much of a choke artist him and KD are because that was the narrative going into these finals and both of them proved the haters wrong. KD came in clutch. Curry's only bad game was first half of game 2 where he played really sloppy and he's been playing good ball.
Another narrative going in, Lebron is the daddy of Curry and KD, and his block on Iggy forever scarred him.
