I guess I hear that, but it seems more applicable to structured "sport" fighting with rules and procedures as opposed to the so-called IRL fight. Boxers bob and weave and duck and keep up their guard because under the rules they can't tackle their opponents and roll around on the ground with them. The IRL fight on the other hand tends to quickly evolve into a ground-based wrestling match with occasional punches and kicks where size and strength dominate over speed and most technique (in my experience anyway).
I did see one IRL fight where a guy used speed and technique to put down someone a fair bit larger. He basically punched his opponent three times in the face while the other guy was still in his "monkey dance" and didn't realize the fight was starting. Game over, that fast. Of course this was in high school and the puncher only served a suspension. Someone does that as an adult in a bar and they're looking at jail time, even if they knew the other guy was going to have a go at them once he worked himself up to it.
Training, as well as sport fighting, has rules because if it didn't, we would all have either quit or died after two days. It doesn't mean that we're wusses, or that we can't- or don't know how to- or are not willing to- fight dirty. It just means that- as my tai chi teacher likes to say- "If you break your toys, you don't get to play with them any more."
If it's a real fight, one must simply switch mindsets and remember that you're not in the ring, and you can do whatever you want.
If a wrestler can competently pin classmates in his or her school for points, s/he will be able to competently pin them on the street while punching them in the face. The skills will carry over.
