taylor still had some handspeed before he was decapitated and what about norrises blazzing speed and combinations, i'd say speed wise it would be pritty even
I guess timing would have played the biggest factor. When Norris was shot, he was really shot. Mosley has maintained alot of his speed and ruggedness. He also fought Margarito with an actual game plan something thats been missing from his corner the good part of his career, which leads me to believe he could have accomplished a lot more with the right mind in his corner.
Norris is naturally bigger than Mosley. He is as faster or faster.....and hits harder. Norris by late TKO.
