A valid point.
Yet, the attributes that one develops in "the ring" are the ones that serve one best "in the street":
Speed, endurance, ability to hit, ability to take a hit, ability to hit WHILE taking a hit, ability to act AFTER getting hit.
Things that CAN'T be cultivated without full contact sparring ( or at least hard contact).
One shouldn't confuse the awareness needed for "the street" with the attributed developed in sparring and competition.
IMHO, if you are trained to fight in the ring then you shouldn't be fighting in the street. You are working towards becoming a "PROFESSIONAL FIGHTER".
Since there are many many elements missing IN THE RING that you find on the streets, ring fighting is the safest way to go. a street fighter who switches over to become a trained fighter will fare alot better than some guy who has never fought in his life. You might say that "the streets" in regards to Ring Fighting is an ENTRY LEVEL position.
