It's worth noting that the Hornets have always been the underdog, even when Jordan wasn't the owner and the team was called the Bobcats. They've never won a championship, a conference, and a division. Besides, they've only reached the playoffs 3 times in the last 18 years. So even if Jordan really wants to improve the Hornets' results, he will need to invest a lot more money and time.
Michael Jordan does have skills and money but he doesn't have the ability to improve and enhanced a team. He is running a team for over 2 decades now.
If I'm not mistaken, he owned first the Charlotte Bobcats franchise back in 2003 or 2004 and they have Emeka Okafor as a top rookie pick.
Since then, the team doesn't improved or even participating in postseason big trades.
