UFC 137 is just a week away, featuring what some believeÃ‚Â to be a welterweight number one contender match between B.J. Penn and Nick Diaz. If you weren’t convinced by our betting advice for the main event, then perhaps the words of Stephan Bonnar, Manny Gamburyan, Tyson Griffin, and Phil Baroni will do your thinking for you. And from the looks of it, you’re thinking B.J. Penn is going to come out on top, because that’s what the consensus seems to be for these pros.
