Bonnar should talk him down. It'd be the only way he could hope to prolong the inevitable conclusion of him getting finished. At least losing by sub would mean he doesn't lose any teeth and/or brain function. But..., even if Bonnar could get Silva down in the 1st round, he wouldn't finish by sub against the superior BJJ artist. If this were to happen, this would be pretty much exactly like Fail Sonnen 2 or the Hendo fight.
