When Marciano and Hagler (just 2 examples) were in training camp, they used to call it "going to jail"
They would lock themselves away from everything - family, friends, regular life.. and focus on the task at hand
Mayweather for this camp actually shut a lot of things down, didn't do many of his pre fight rituals.. Wanted to focus 100% on the fight
Ever since Manny became an icon in his home country and especially since he pulled a Fedor and got super religious/truly believed the fight is "God's will"... he has not been the same. Lots of hanger ons. I think after his amazing career and coming from such poverty.. When he finally made it, after a few amazing years at the top of the sport, he just got tired. On top of that, he seems like he is focusing on everything BUT the fight, aside from the actual training, he is surrounded by everything except the fight itself
Just an opinion. IDK
