Yes, this could be done at all four weights, considering a fat, shot Morales was able to be competive with a young Danny Garcia
Arguello stops Morales at any weight. For one, Arguello was just the better and greater fighter. For two, the styles favor Arguello. And who cares about giving a young Danny Garcia a tough fight . The Arguello who stopped Rooney and fought Pryor in the first fight would beat the fuck outta Cherry Garcia.
Not really. I think people underrate how much of beast Arguello was at 126. It's where his power was the most devastating. Morales wasn't all that at 126 - he had his apex performance at 130. But unfortunately for Morales, Arguello at 130 was God-level.
AA is simply a better fighter than Morales.. It would be competitive, but Erick is taking way too many punches to win this one
