Of course he can still overtake Jordan, his career is not done yet. Mentioning Jordan’s perfect finals record doesn’t tell the whole story, LeBron wouldn’t suddenly be better if he was 4-0 in the Finals instead of 4-5. Jordan lost playoff series too even before they got to the finals, and the Warriors LeBron faced are a few levels above Jordan’s competition back then. People with a “Jordan forever #1” mindset will probably end up at the wrong side of the argument sooner or later, be it with LeBron or another GOAT candidate in 10-20-50 years time.
Oh and he’s already easily past Kobe. Don’t think many people would have anyone else but Jordan over him at this point, especially if he wins #4 this year.
