Here is my answer to how you deal with a south paw,taller opponent,bigger opponent,faster opponent,more skilled opponent.Since i have introduced the Jab response drills to my already skilled students who slip,roll and fade back we have hit a new level of skill.Rafael Delgado of Evolution MAFA boxing teaches the core and fundamentals needed in boxing,mma,muay thai.It remains the same with minor adjustments to weight on the front leg only.In my opinion,and before my very eyes i have seen highly skilled mma and muay thai guys getting destroyed with a simple jab.
