At this stage of their careers, yes. He has done slightly less himself with much less for teammates.
It is slightly his doing as he decided to team up with two players who are just absolutely terrible for him. Dwade and Bosh are so much worse than they were supposed to be it isn't even funny. Wade has been washed up all year, and can't even shoot a mid range jumper. His entire offensive strategy is to slam his body into defenders in a 1 on 2 situation and hope to be fouled while throwing the ball up and hoping to make the bucket too. Not to mention Dwade and Bosh are TERRIBLE at hustling and team basketball and give up & fold at the slightest bit of adversity.
Bosh is afraid to play inside and only ever wants to take jumpers, which he is not very good at in the first place. Both players are high volume scorers. LeBron would do better with a real post presence, a couple three point shooters, and a guy who was automatic from mid range.
It should go without saying that the years in Cleveland were even worse. LeBron took this starting 5 to the NBA finals early in his career:
PG Eric Snow
SG Larry Hughes
SF LBJ
PF Drew Gooden
C Ilgauskas
^^^That is unbelievable.
Jordan had more championships at this point, but his front office was so much better at giving him players that fit how he played and had great chemistry. Jordan had Pippen his whole career, and Rodman for the last few championships plus outstanding role players at all times.
Jordan also didn't have the ridiculous, unprecedented pressure that LeBron was forced under. People expected the '94 Bulls when he was in Cleveland and the talent just wasn't there. When he did all that stupid **** and went to Miami the first year it was even worse. Jordan didn't have to play his entire career in the shadow of the GOAT.
I'm not sure I believe what I just wrote, but I think I gave a decent devils advocate.
A lot of this makes sense, and as a Bulls fan from Chicago I'm clearly biased, but it doesn't explain why on LeBron's most talented team ever (a team as talented as many Bulls teams), he would have the largest scoring average drop in an NBA finals history. That's by far the biggest difference.
Jordan sets the playoffs bar CRAAAAAAAAAZY high. If we're talking regular season or career stats it's a discussion. If we're talking playoffs and finals Jordan is the most dominant ever by far. It could be decades before someone can touch his playoffs scoring, even a very young natural scorer like Durant already has no chance at it.
