LeBron James has been statistically outplayed in 30% of playoff series vs just 5% for Michael Jordan. In addition, LeBron was statistically outplayed in 14% of series (8 of 57) by a teammate vs 3% (1 of 37) for Jordan.
1 of the 2 times Jordan was statistically outplayed, he was injured and his minutes were limited but he still had a higher gamescore per minute played than Pippen.
It's very common for LeBron fans to use box score stats like pts reb ast to claim LeBron is the goat. The problem with that is it ignores the full box score stats and ignores any stat inflation that is occurring. If you don't adjust stats for an era, the best players ever would all be the top players today.
Gamescore is a single value metric that evaluates the box score stats - pts reb ast stl blk tov fouls & shooting efficiency. To handle the stat inflation that has occurred, one method is to compare that player to the other players in that same series. Not only adjust for era stat inflation but it adjust for how that series was played (a slow pace defensive series vs a high pace offensive series).
If you're going to use boxscore stats, then very little reason to not accept gamescore. Like all stats, it's not perfect but you will likely not find such a massive gap of 30% vs 5% between two players being compared where the player outplayed in 30% of series is better. No surprise then that Jordan has a higher BPM, ws/48, raptor, etc as well. Jordan's on-off net rating has also been recorded for his full postseason career. MJ has a 18.1 net rating on off. LeBron is 9.3 net rating or 10.5 net rating through age 35, the same age as Jordan in his last postseason.
