Haha I love it. It's a fan-driven sport, and obviously the fans want him to do it.
I'm okay if it takes a little blackmail from a charity to get it done

The only reason he hasn't done it anyways is because he's afraid he'd get beat, which he probably thinks would hurt his legacy. If he enters it his popularity would virtually guarantee he wins it anyways, unless he totally bombed all of his dunks.
