makes sense to me, for the most part it's all short powerful shots that are no nonsense. No flower. The flower looks good but the quick stuff is what wins.The huge irony is, what these guys used was what a lot here would call "kickboxing".
As for being tough and getting tough. I think it's a good idea. I'm not saying you shouldn't work on your defense but working with all these fancy blocks and dodges often times just gets you into trouble, sort of sets you on the defensive. In real fights atleast, taking the shots makes or breaks you.
