After the Mayweather Marquez fight, in a magazine over here in the UK called shortlist, it showed Mayweather taking a completely flush shot on the nose from Marquez, perfectly clear. Now if Marquez can land perfectly clear on Mayweather, then I'd say Khan is in deep water for sure but probably his speed will get him out. I'd even go as far as saying that Khan is faster than PBF, just without the chin..... Ha
