Bradley is a short fighter. Everyone he fights is taller than him. So khans height may not neccessarely be an issue but khan does use his height very well. I wouldn't put too much stock in khans performance last night when comparing him to the other three top fighters at 140. Maidana defeated an undefeated ortiz. Alexander koed urango and Bradley took witter holt and Peterson. Khan beat paulie. You see the difference? The other guys are going to touch can with power and speed and pressure and skill. Let's see what he does next. Last night was an A- performance for Khan but against Bradley he will need to be A+.
