Re: Anything wrong with being a brawler?
Being one dimensional is never optimal. You can be a banger, but still use skills. You mentioned older Mike Tyson...why not try to be like Younger Mike Tyson?
Moving out of the way of punches or blocking them is preferred to taking them. I'd also recommend dropping weight. At your height, that's pretty heavy. Guys that weigh in 170 are probably legit cruiser weights. Who walk around at 190, and are like 6'3.
