If you get the chance ask him where the "PLASTER Blocks" went to that he claimed fell from Antonio Margarito's wraps I tried he just turned his back & walked away.
I think you have to include ''the Corner" who was best during a fight. Thinking on their feet, making adjustments for the fighter, motivating etc. Arcel and Dundee are the two greatest Cornermen. Freddie Brown and Jack Blackburn the best teachers. Emanual Steward, Freddie Brown and Eddie Futch for adding to a style, breaking down an opponent's style. If nailed down to pick one guy it would be Freddie Brown. Not the best with beginners but hehe cou add to a style of a seasoned pro. He taught his fighters how to fight inside.
Strangely enough, Vito Antuofermo felt the opposite of Freddie Brown. He felt he was not a great teacher, but an exceptional cornerman. I guess it's in the eye of the beholder.
