What has happened to it throughout the years? It was live when he fought Marquez. Credit to Mosley for keep his right hand up to block it. Mosley wasn't aggressive either, so Floyd's check hook wouldn't be available. Floyd lands a 2-4 check hooks on Ortiz. Cotto kept both his hands high. Don't remember too many check hooks in this fight. Floyd would get em off in combos or exchanges. It finally came back out in full force against Guerrero.
