I saw Jordan miss more than just the All-Star Game dunk since his most recent comeback. As a Jordan fan, it nearly made me blush everytime I had to witness his faltering athleticism.
But @#%* that $*@# about his long overdue re-retirement. It hasn't been like he's Stephen Hawking putting up and down the court. He's noticably slower, and he's lost some hops, but he still looks like a capable professional athelete out there.
Besides, the obvious advantage he has out there is his vast knowledge of the game and the way that affects his teammates.
