Bonnar has really underrated BJJ imo. If he uses the Chael Sonnen game plan in taking Andy down, he may actually be able to pass his guard into side control and go for a kimura or a head and arm triangle.
It's really not out of the realm of possibility.
That being said if I had to put money on it I'd say Andy by TKO round 2.
I've always thought Bonnar looked liked Nicolas Cage.
Now I know their acting skills are on par too!
