street fights

I have noticed that in street fights when the first punch is thrown the person on the recieving end normally (in my experience) leaves his legs unguarded and out in the open. Are there any moves to take advantage of that? Thanks.

Are you looking for an additional target with you as the attacker?

my expirence of street fighters is that alot of them do kickboxing or at least fight like kickboxers. a lot of local gangsters do kickboxing at the local gym and every hard core street fighter guy i know does kickboxing

I can't see gang memebrs caring about cardio, weights or diet. Or having martial discipline.

I can see them shooting someone though.
