I agree more with Mr. Lawson in this regards for the following reasons: 1) Bigger gloves allows for different guards to cover more areas, such as holding the gloves on the cheeks. Also, protects the hands more which leads to more head punching as opposed to body punching. You said there was no mechanical difference in your friend, just that you got hit more. That is the WHOLE POINT, he is utilizing a style and approach based on larger gloves. If all fighters had to fight with 4 oz. MMA gloves (or the 5 oz gloves Jack Dempsey wore) in boxing you would slowly start to see an evolution of guards and defensive work so you wouldn't keep getting hit more. 2) Ring Size: smaller rings lead to more engagement with the fighters and less moving around and running. This has lead to different styles of boxing based on the ability to move a lot more. This was one of the key factors in the Jack Dempsey v. Gene Tunney fight. Dempsey always fought in a smaller ring which favored his bulldog style of moving in and taking out an opponent. Tunney used a lot more footwork and moving around to avoid that. 3) Neutral corner: Previously, a fighter could stand over the downed fighter and as soon as they started to get up could engage again. 4) Clinching: Now it is a strategy used to smother another fighter or to get the fight back where you want it on a close in fighter because the referee will step in to break the clinch and separate the fighters. Before the rule change, if you clinched up you were eating kicks or getting tossed onto the ground. It was not a "safe zone" for the fighter. 5) Round limits: Top end of a pro fight is 12 rounds. Before the 80's when Ray Mancini killed a man in the ring, it was 15 rounds. Yet, before the 1920's there was no limit to the rounds. This definitely effects how you train and your approach. How many times have you heard the complaint about just boxing to win the rounds and getting a decision and never knocking out a fighter? Old school, the only way to win the fight was to make it so the other guy couldn't continue. All of these factors influence how boxing is trained and utilized. All of it develops into its own separate strategy. Looking at how it is done now and saying there is a common thread to all of them ignores how they were all implemented from the same rule pool. Rule set and environment will ALWAYS change how a martial art or combat sport is done and it will always gravitate to maximizing itself in that rule set.
