I follow MMA a lot but I've never fought professionally or as an amateur, just a few scuffles in "da streets" as a teenager. 171 vs 174 is basically a 1.5 kg difference which, in normal life, is basically nothing if you are getting into a physical altercation with someone. Being 1.5 kg's or 3 pounds heavier realistically does not give you a serious weight and strenght advantage over your opponent, as far as I'm concerned. I'm not saying fighters should fight at whichever weight they want and, to me, making weight means being professional and respectful towards your opponent's efforts. It is also true that sometimes things just go wrong or you're not getting good technical advice, so the fighter is not always at fault. What's your opinion on this, can a few pounds influence significantly the outcome of a professional fight or is it just about the fighter and maybe his team not being serious and professional enough, if not, at times, incompetent?
