Arguello should be #1... 2, at the worst. Arguello was more dominant at the weight than Nelson, would have dismantled Nelson.
Alexis had quit the division by April 1980. That two fights and four months gets him the number four slot shows how brilliant he was.
It's insane, and look at how many action fighters reside there as well. Even the will of the wisp boxer that was Camacho was exciting at that time.
Arguello's run at 130 is possibly one of the best, concentrated streaks ever recorded in the division. Much of it, however, occurred at the tail-end of the '70s. His Number-4 rating for the '80s, writes a love-letter to his previous decade, I suspect, and marks his two solid wins in 1980 (perhaps not undeservedly).
