I agree, somewhat, but, the records for timed events, height, and distance have been reset many times since the old days. That has to tell you something. 5 ounce gloves are very hard on the hands. I’ve personally knocked out 5 opponents with 16 ounce puff gloves when I weighed 170 lbs. As far as heavyweight boxers, Rocky Marciano was probably the best ever, IMHO. And no, I’m not Italian.
5 ounce gloves are very hard on the face of the opponent.
The pillows they wear today less so.
You haven’t commented on the steroids they pour into “athletes” today.
