You're correct Oli, you need to learn how to deal with grappling / being taken to the floor but what you really require is a system which teaches you how to avoid being taken to the floor or, having been taken down, how to get back to your feet asap. BJJ specialises in ground fighting, i.e. fighting from the floor, not the two aforementioned skills and especially not the latter.
As taught to us over here, there's an awful lot missing from the art and sadly once again, it's started to become watered down.
Still many guys regard it as the ultimate system for self defence, based largely (as everything is these days) on the perceived effectiveness of the system via the ufc, mma, etc.
When asking instructors over in Brasil about it's effectiveness, i.e. would they resort to grappling in a true self defence situation - nfw, bearing in mind the high liklihood of a blade being pulled and utilised over in brasil. As I say, to those guys it's just a game and everybody plays it, to us it's somehow been protrayed as the ultimate in street self defence. Very clever marketing imo which started with the formulation of the ufc.
I myself love a roll, but with my background in other arts it scares me to know just how exposed a system like bjj actually leaves you.
