It matters to a certain degree. It isn't the deciding factor but it certainly makes a difference if one person is 5'4 and weighs 140lbs and the other person is 6'4 and weighs 220lbs. Especially if they are both fighters. Now, if the little man is a fighter and the big man is just big, then the little man will win. But that isn't the discussion. The discussion is on whether or not we think we could take this guy. I asked for his stats and so far you have not provided them. Why are you getting emotional, as if you know this guy? Why are you trying to throw the conversation off by insulting people for answering the question? Did we not answer in a way that you would have preferred? Do you just make posts in hopes that people will say exactly what you want them to say? Seems like a dull conversation, if you ask me. I'm guessing that he is 5'4? Somewhere around 140? If this is the case, then it makes a big difference. If he were 6'4 and 220 then those same kicks would be devistating and my answer to the original question would be no. But if he is 5'4 and 140 then those kicks will sting, at best, and the answer is yes.
