How much time is actually devoted to stamina and cardio by boxers of today?

This could a very interesting thread.

long distance running (Marciano would run 10 miles per day in the week before the fight) has been dissed and dissed badly ion the past 12 months by major health experts and trainers for actually tearing down the immune system and causing repetitive joint and tendon injuries/weakening joiints. The young plumpy boys fighting now aged 20-30- are really loving that announcement and cutting back on their roadwork. Focusing on "strength training" and less on cardio

this is a fact as I have visited 2 gyms in the Brooklyn area this past month and heard this directly from trainers.
