He fought Baldimor who was meh. What about Williams, Martinez, Margarito, Thurman, Porter, Brook, etc. When will he fight an actual large Welterweight and not old featherweights and lightweights?
He's not a career WW himself. Did you miss the fight in which he took the current MW champion of the world to school? The fight where he was outweighed by almost 20 pounds on fight night? Would a win over Keith Thurman really change your opinion?
