Not trying to argue, but just curious: was boxing as big as football is now in the US? I'm not much into sports in general, and I wasn't around when boxing was big (or just completely missed it), so I'm lacking context.
Boxing was the football of the 1920s, with saturation radio and newspaper coverage, and became the top sport of the early broadcast TV era. It has been declared dead or dying at regular intervals despite being a solid performer into the pay-per-view era. Like football, it would probably be somewhat safer if its "protective" gear was reduced or redesigned.
