Dear Michael, from all of your fans that grew up watching you. School this guy like there's no tomorrow.

Robert Pera joined the ranks of NBA ownership last fall when he closed a $377 million deal to finalize his purchase of the Memphis Grizzlies. In that time, the Silicon Valley billionaire has presided over the revamping of his team's front office, locker room and coaching staff, watched his new investment have the most successful season in its history, and even joined a Grizzlies message board just to chat with some of the team's die-hard fans. It's been kind of a big year.

The 35-year-old founder of Ubiquiti Networks has started to display a new wrinkle over the last few months, though, an apparent interest in mixing it up on the court with NBA players past and present. He's talked trash to Dikembe Mutombo, matched up with Toronto Raptors own Landry Fields and even challenged noted Grizzlies defensive stopper Tony Allen to a game of one-on-one for charity.

That face-off has yet to materialize, and apparently, that's left Pera in the market for another source of high-level competition. I do mean high-level, when Grizzlies fans and Pera's Twitter followers began suggesting a game with fellow brash tech billionaire and Dallas Mavericks owner Mark Cuban, the Grizz boss scoffed and set his sights toward another owner with a significantly more impressive on-court resume.

Pera has called out Charlotte Bobcats owner Michael Jordan, who recently made some waves by identifying a handful of all-time greats, including LeBron James, that he's quite sure he'd have been able to take down in one-on-one games in his legendary prime. Jordan's just a bit past that prime now at age 50 although, Jordan can still throw down and the apparently-quite-confident Pera is willing to stake a cool million to the charity of Mike's choice on his ability to take advantage of the 15-year age difference between him and the greatest player of all time.

I say take the challenge Jordan, we all know you can school this guy. Especially since you were talking about making a comeback this year.
