If Garcia steps into the ring motivated and in good physical and mental shape, I think Benn has little chance of winning, Ryan is the better fighter of the two. It’s a different story, however, if Garcia shows up looking the way he did against Romero. I wouldn't underestimate the toll of Benn's weight cut, either, while it’s true that boxers at this level are looked after by top doctors and nutritionists, we’ve seen fighters turn into zombies in the ring. And we don’t have to look far back to recall examples, we need only think of a boxer Benn knows very well: Eubank Jr.
This is a Mayweather-vs.-Pacquiao-level matchup for the most unlikable fighters in the sport. Probably two of the top 5 most detestable gobshites in the sport P4P going at it for a legit world title. I think Garcia wins easily because Benn looks horribly drained, and he's just not very good at all, especially defensively. But then again, neither is Garcia. I can see Garcia catching him early, though. RyGa also got comprehensively outboxed by a guy with absolutely no fundamentals at world level, though, so who knows how it goes. If I had to guess, I'd say Garcia within the first 3, left hook, similar to the one he caught Haney with in round 1.
