Now that he's 50, there are probably quite a few people in the world who could beat Michael Jordan in a game of 1-on-1. We're guessing that MJ could still hold his own against just about anyone out there. But he's not unbeatable like he used to be.

That said, we're going to go out on a limb here (not really) and say that MJ could beat any other NBA owner in the league in a game of 1-on-1. But Grizzlies owner Robert Pera wants to test that theory by playing a game of 1-on-1 against MJ for charity. Recently, some of Pera's Twitter followers suggested that Pera challenge Mavericks owner Mark Cuban to a game of 1-on-1. But Pera revealed that he has his sights set a little bit, er, a lot higher.

As of right now, there has been no response from MJ. But we think he should call the 35-year-old Memphis owner and accept. It would give him the chance to show just how dominant he still can be. And it would be for a great cause. What do you say, Mike? One more game of 1-on-1 for old times' sake?
