Yow! Ganigan would raise the roof with Arroyo. As much as I liked Arroyo, I expect that Andy would be hammering away with right hooks and straight lefts to Harry's lanky body. Arroyo would have to stay the hell away from him, wait for him to tire out, then drown him in deep water. I don't recall Arroyo as having the mobility potential and blinding handspeed Hilmer Kenty displayed against John Montes. Arguello had difficulty with Ganigan's "weird style," and I suspect the much less experienced Arroyo might opt to slug it out with Andy. I'm going way out on a limb here, and speculate that Ganigan would take Harry out early, much as he did O'Grady. There's no way I'd ever put money on the outcome of a matchup like this though. Good matchmaking!:good
