If you do not have the basics on how to handle different styles, who the hells fault is that then? YOU BOX TO YOUR STRENGTHS! You clowns ever heard of the sweet science?
The sport(MMA included) would be pretty boring if everybody fought the same. Boxing and MMA benefit from guys like Lara, Rigo, Machida and Cung Le in much the same way as Rugby benefits from teams like Italy and Fiji. They all bring a different element that makes for interesting and intriguing matchups.
