What MMA Needs

Is there a moment in MMA like this?

ESPN has an article on it's site about "Nine reasons to be excited about MMA in 2009".
And Tito Ortiz is one of them.
Which got me to thinking, what MMA needs is a "Muhammad Ali".
A charismatic figure that can draw the attention of the world.
Most MMA fighters seem to be " get the job done" kinda people, and while that's all well and good for the sport, it doesn't do much for picking up TV viewers.
MMA needs a Ali, or a Sugar Ray Leonard figure.
Heck, look at Hulk Hogan in wrestling, he was everywhere and helped elevate pro wrestling from "smoke filled bingo halls" to NBC and USA.
But they have to be careful, you can't hype the line too much.
If you do, MMA turns into Pro Wrestling, all flash and no substance.
So is there anyone out there that can become MMA's version of "The Greatest"?
