Oh and BTW...
I've also heard a lot of people knock the act of "going for a submission" in a real fight. A "submission" IS NOT a move, or technique. It is the act of one opponent asking for mercy because they realize that they are about to suffer very painful or debilitating damage or even death at the hands of the person they are fighting. In sport situations, of course the requested mercy is always granted, and the fighter lets go after the "tap out". In a real fight, if I can apply a choke or joint lock on the guy, who says I am going for a "submission"? I may be getting ready to knock him out. Only my method of doing it is with a choke instead of a punch. Or I may just not let go of that kimura lock, and if I don't, once I finish it I can let go and I GUARANTEE he ain't fighting me anymore.
Perhaps I'm missing something, and forgive me if I am, but it seems to me that they are all one in the same. Anything you do, regardless of whether or not its on the ground or standing, could be classified as a technique.
Now, just like with a standing lock flow series, people often say that they'd never use all of those locks in the series, and yes, they're right. Its designed to teach a flow, and give options. So, I don't look for locks, but if an arm is there, I may be able to pull off lock 6 from that series, because that is what presented itself to me.
My thought is...sure, if that arm, leg, ankle or neck presents itself, fine, take advantage of it, but I certainly wouldn't sepcifically stay there waiting and hoping for it. My main goal should be getting back to my feet.
And about ground fights taking a long time...that is usaully only if both fighters are equally matched on the ground. Either they both don't have a clue what they are doing, or the are both good. UFC style 15 minute ground fights don't usually happen that way in a real fight. A skilled ground fighter whose opponent is not as good as him can finish his opponent VERY quickly...
I'm sure this is true, however, to intentionally take the person there...well, I think you know my thoughts on that.
Of course, under the optimum conditions, anything is possible. I wouldn't expect someone to take me down in a crowded bar, anymore than I'd expect someone to do a jump spinning back kick.
In the end....I love BJJ. I enjoy rolling, I enjoy the kick butt cardio it gives you. I think that its very important to know the ground game, even if its the basics. I just feel that if there are other means to finish something, why put yourself in a potentially worse position than if you were standing?
