Yeah, that really isn't a valid comparison at all. Anyone who compares Maidana and Guerrero to Rios and Algeiri are REALLY reaching, haha.

The Algeiri fight reminds me of Floyd's fight with Baldomir: both fights were opportunistic by Floyd and Manny, as you had an unknown and inferior fighter pull off a big upset and grab a title. On paper, both opponents had no chance.

The big difference is, at least Baldomir was the undisputed WW champion after beating Judah, making him technically ranked higher than Mayweather at WW at the time of the fight.

Algeiri managed to grab a trinket, but is far from the #1 140lber in the world, so technically even the Baldomir fight was better than this one.
