The average person has ZERO takedown defense, assuming you are starting with both guys empty handed and an experienced grappler vs. a regular guy who occasionally works out. Some wrestlers and probably BJJ guys to can shoot in super quick, not to mention an effective set up, that by the time the average guy realizes where he is, he's allready been speared into the concrete neck first and the wrestler/BJJ guy is working on the pound part of the ground n' pound. Watch Shamrock vs. Zinoviev....ok, its in the ring, but both guys are fighting and Zinoviev is in great condition and a professional fighter.

You're assuming that every BJJ guy is going to fight like he's doing sport JJ and doesn't train in other arts. Your points apply well in that case. If the BJJ guy is slightly motivated and has experience, whose to say that he's not carrying his own weapon and won't integrate his weapon with his grappling.

Anyhow, decent points made.
