Should championship fights go back to 15 rounds?

I think so but the reason they were dropped still remains. Economics not safety and the overriding problem today would be the fact that 80% of the fighters today could not fight 15. Entire training regiments would have to be changed. Half of the elites today are gassed by round 6.

I wonder how much time is actually devoted to stamina/endurance/cardio training by the boxers of today.

Do they spend most of their time in the gym and do "a little running here and there" and underestimating its importance?

Interesting question because new gens always go on and on about science, technology, sports medicine, nutrition bla bla bla and the results show anything but advancement. In many ways its devolved. Its as if they train for highlight reels and 6 round fights. I doubt a plan B is ever mentioned.
Its a knockout or bust era. Boxers get ignored or labeled boring. Its asinine.

Instant gratification. Boxing has become an app on a tablet lol.
