It would just seem that a glove covers more mass to jolt and shock the brain in the skull. Concussions may actually come faster and with longer lasting equilibrium problems while close to bare knuckle more risk to lacerate and break bones. I don't think majority of boxers who have suffered hand damage would ever favor lighter gloves. Boxing is just upfront about the impacts as it's clearly on display, but more and more It would seem pro football is up there with long term and brutal impacts of repeated blows to the head and concussions. You may not train to punch a guy but you train to break the body and heads hit ground or brain just bounces off the skull same result often. They are on the road to turning football into flag football as result.
