(not that you were implying that, or at least I hope you were not).
I would pretty much agree with you - so your right I wasnt implying that.
Sport fighting is indeed what its name suggest and they train like any other athlete to be proficient, etc.
Krav Maga, etc. has its purposes, as you mentioned, for a whole different scenario.
And then there are regular brawls. The guys that take all of this stuff who are not 'sport fighters' and the rules can truly be flexible...depending on the set up of the situation and what is happening at the time. (its the great unknown to a certain extent.)
I have been in a couple of those situations - (regular fights...which really are not regular, but again depend on the situation at hand and its true immediate danger.)
Good post - its good to clarify.
