also...I know you don't want to admit it, but the ring is not the street.
An ma who spends all his time training for the ring will beat the ma who only spends part of his time training for the ring...in the ring.
If weapons are involved, you use a longer guard...if multiple opponents are involved, mobility is much more important than ground fighting...if if if. In my school we train for everything...maybe we won't be the best at anything, but it certainly keeps it interesting...
I remember once arguing with Knifefighter about the validity of the standing armbar...he said it's cr*p, then I see a dog bros. vid he posted where 1/4 of techs shown are armbars...he says, well, dynamics of knife fight are diff then MMA fight. No sh*t...that's the point. You can't be the best at one if you learn both...but really, for survival and for fun, it's better to learn both. So sorry, I'll never have a vid of my MMA fight.
Actually I have plantar fascitis (sp?)...need my arch support, only full-contact venue I'll probably ever be able to enter is boxing...probably won't...does that really prove anything?
