Re: Billy Petrolle vs Alexis Arguello
This one goes the championship distance. If it was stopped, Billy was halted a couple times by damage to his eyes, and Alexis could certainly inflict that kind of injury.
However, I think the difference here is the combination of Arguello's height, optimal use of reach, and refined boxing skills. Vilomar Fernandez and the wildly unpredictable Pryor were able to screw him up with movement, while I expect the Fargo Express to go right after him, like Ganigan and Elizondo tried to do. Remember, Alexis was a counterpuncher, so Billy might play right into his hands. Mancini might offer a clue as well to what Arguello-Petrolle might resemble.
Certainly, Billy could pull off a knockdown or two, but it's not as if Alexis never got up to win in those situations. I think this one ultimately comes down to skill and technique. As tough a scrapper and hard a puncher as Petrolle was, I think Arguello's class makes the difference against a more orthodox performer than Pryor and Fernandez were.
Enormous respect for the Express, who uniquely stopped Battalino, was the first to stop Berg (nearly three years before Canzi turned the trick), and decisioned Canzi and McLarnin, but I believe El Flaco Explosivo is a bridge too far for Billy.
