I never actually saw Jordan play pre-Wizards, so I don't really have much of an opinion on the comparison. However, Jordan's second best rebounding season would be Lebron's 8th best, and Jordan's second best assist season would be Lebron's 7th best. Jordan had one unwordly season for triple-doubles, but Lebron has maintained a pattern of being an elite rebounder and assist man for nearly a decade.
Here's an interesting stat though. Lebron is at 56.5%/42% shooting this season. Both percents are better than Jordan's best season. Lebron's FG% has increased every season except 06-07, when it dropped .4%.
The pro-Jordan statistics are points, career FG%, steals, and rings. The pro-Lebron stats are rebounds, assists, and career 3PT%. A statistical comparison is tough to make though, because they play different positions (if Lebron can even be said to have a position) in different eras on different teams, and Lebron is apparently still improving and has a long time yet to play. The separator right now is Jordan's "clutchness", but an honest look at last 5 minutes, game winning/tying attempts, and "transcendant games" shows that Lebron's resume is much stronger there than most people assume.
