I think Arguello outworks and overpowers Locche, although Locche will definitely make him miss a lot.
Locche,the only way I see a strat working vs Locche was to outbox from a distance and try to hit him without over commiting, problem was, Arguello would not
There are quite likely a good few 135/140 boxers in history who could measure and time Locche. Arguello is one of them.
