i'm a fight fan. i watch everything, k-1, dream, strikeforce, boxing, EVERYTHING. I have friends who are professional fighters, 7th dan black belts in taekwondo, hapkido, boxers, muy thai kick boxers, etc. and they all will tell you the importance of striking! a superior striker will beat a superior grappler more times than not if, and that's a BIG IF, the fight stays on two feet then

. if that boxer gets taken down or his scramble ain't on point, then he's in for a long night. it seems with proper training you could learn to defend a takedown, how to scramble and not give up your back, arm, leg, etc....but years and YEARS of focus on solely throwing hands, placing punches accurately, proper technique and throwing punches CORRECTLY (which a LOT of MMA fighters DO NOT do) can not be taught in a matter of weeks and can not be taught when you are steady being crammed with other things that have to be learned as well.
i respect BOTH sports and imho neither is superior to the other, point blank period.
