Floyd Mayweather should stick to what he's been doing for 20 years. A lot of people make the mistake of changing later on. The problem with doing that, is you have no experience. Pretty Boy Floyd has decades of experience. Money Mayweather has like 2 years. There's no comparison. The most you should ever do is incorporate your new strategies into your established victories.

Pretty Boy cannot possibly lose to Marquez. Pacquiao had a hard time with Marquez because he is hyper-aggressive. It plays directly into the counter-punching strenghts of Marquez. If you don't punch, or you can't be counter-punched, counter-punching has no effectiveness.
