Your best bet is to avoid a street fight if at all possible... If it is not avoidable, you do what you can to survive! I have fought "many" times in street fights and the last thing I would do is go to the ground with anyone, as long as I can dictate that part of the fight. You never know who is going to jump in, you may be fighting on concrete, etc... And the first rule to street fights is there are no RULES!!! It is all about survival! You don't know if they or one of their friends is armed (knife/Gun/knucks/club, etc...) If you are not a fighter, and even if you are, your best bet is to test your skillz in the cage or on the mats. Never the streets! If you find yourself in a situation where you have no choice, then defend yourself! But don't hold yourself to rules that don't exist on the streets! People will bite, scratch/gouge your eyes, kick/grab your balls, what ever they can do to win/survive. Be the smarter person and walk/Run the hell away, and get to live and train another day
