This is all about Broner and what shape he's in, or more to the point, how serious he's gonna take this and indeed his career.
when he's in the ring , he's tough and shows a lot of heart and guts, that's not the problem.
his problem is what he does outside the ring. I don't think the bookies odds are stacked against Broner because Garcia is seen as that much better, I just think that they don't trust Broner to come in shape and do it right.
If there was a guarantee that Broner conditioned himself right and was in shape, the odds would probably be the other way around.
