Are you telling me that what you train for in the ring will be the same thing as fighting or defending against someone who may have a knife, bat, stick, gun, has friends with him, when you're in an alley, alone in the parking lot when it's dark, or maybe weighs more than 50lbs. than you?
The major difference between boxing and martial arts is well...boxing is a SPORT whereas in martial arts...it's well, martial arts. Usually a good school will teach you to apply the techniques you've learned against numerous situations and not just one opponent.
"Guys, a fight on teh street or in the ring is really not that different."
