Obviously, it's not even a question as to who the better fighter of the two is. It's just a question if Cotto is too big for Arguello. Or, is Cotto just too hittable for Arguello even at 140? I think Cotto is too hittable, and despite being smaller, The Explosive Thin Man had too much firepower and accuracy for Miggy. Aerguello by stoppage.
Cotto was bigger but still a bit too fragile and hittable to handle Arguello. Move up to 147 and then I think the size difference would turn the tables in Miguel's favor.
C'mon ... Cotto was coming in as a junior middleweight at "140" How do you guys not see how much bigger he'd be? Be the biggest guy Arguello ever fought by miles
