Well!! if you can't submit the BJJ guy only rolling. what makes you think that you could beat him in a real fight?
Why would I think I can beat any skilled, trained fighter of any discipline in a fight? I'm not a professional fighter
What exactly is your point here? or is this just a way patting yourself on the back?
For me it comes down to skill level.
If a dude is a very skilled, experienced fighter of course he will fuck up 99.9% of all civilians....no shit.
But if it's just a regular dude who doesn't have a great deal of experience yet, that will just come down to who's naturally the tougher guy.
a year of BJJ training won't make you a badass
