Right. But my point is that Lebron chooses to use the vast majority of his possessions as the PnR Ball Handler and as an Isolation scorer. Both of these play styles are certainly not his most efficient and are also not the most efficient play styles in the NBA even if he were in the top 90s percentile in both, and he isn't.
So my point is that we can't have the most efficient offense when Lebron dominates the ball so much and actively decides to run the majority of the offense as a Ball Handler and in Isolation. This makes our offensive efficiency basically be capped at 0.96-1 .PPP when we choose to run the offense like that and makes our offense really dependant on whom he shares the floor with.(sacrificing defense for spacing, etc)
The reason our offense was so good in 2016-2017 was also because of Kyrie... you can't ignore that Kyrie is a ridiculously efficient scorer, especially in Isolation. Another reason is that it's still at the top because of the consistency that Lebron provides as an offensive threat(Most consistent player in the league, by far), and also he is so unbelievable good as a Roll Man, Cutter and in transition that it boosts up our entire offensive efficiency, even when he doesn't doesn't use those play styles nearly as frequently compared to the rest.
So as long as Lebron decides to play like this, he is more of a floor raiser rather than a ceiling raiser (Like Curry). He can make any shitty team a top5-7 offensive team, but would he elevate the Warriors if they chose to run the offense through him in Isolation/Ball Handler? probably not... So as long as he chooses to play like that we are basically somewhat capped, and that's my issue. And that's a decision, not a limitation.
