I'm so glad that this video accounts for silly things like camera angles and parallax to accurately measure his head size so precisely.
Because he gets punch on cheek bone AND JAW LINE for a living.Floyd's pretty face rarely get's clocked very suspicious he looks like what you just said.
To be fair, Marquez of 2008 was a much better fighter than Cotto, Margarito, Hatton, Clottey, Mosley, De La Hoya, and Diaz. He's not facing better fighters, he's facing bigger fighters.
