I don't believe the Cotto fight was Floyds prime, but I guess I included Leonard for Hagler.
I never saw anyone wear Floyd down, even his worst performance was just a close fight. I saw Hagler outboxed a bunch of times.
The Floyd that debuted at welter, around the time he fought Baldomir, wouldn't have issue with Hagler. Hagler needed to be able to get a guy to slug it out and he was great at that, but great enough to force floyd into a war? No way. It'd look the like Canelo fight, with a faster pace.
Plus, look at how Leonard mind fucked Hagler, imagine what Floyd would do to him.
