Roach & Ariza.. Get to learn a lot sparring with Manny Pacquiao, Khan & Benavidez. Then jump ship to Garcia because i'm not getting enough attention, learn a shitload from Donaire (who will make a really good coach) Spar with Margarito and put a beating on him every session (That's for Cotto, puto) Use what i learnt from Wild Card to beat Benavidez & Khan after Pacquiao retires. Mayweather's be saying i don't know **** about boxing as Floyd extends his vacation.
Nacho... has had more champions and some seriously skilled one's too... Not just one guy like, Pac, Mayweather JR..
Love Garcia but I would want a trainer that will know when I need the stop when I don't have the pride to. But I wouldn't ever want McGirt as my trainer and I wonder why fighters hire him for the most dangerous fights. He's like the other extreme to Garcia. I agree with him pulling Brewster and Gatti out but he could've let Malignaggi finish the Hatton fight.
garcia, because you get to spar with brandon rios and nonito donaire. they're better than manny and khan! plus you get to see elie sechbach every day!
Nacho Beristain is probably the best, out of the list Garcia or the Mayweathers. Roach is well overrated, he gets all the best boxers and teaches them basics and gets them in shape. Technically he doesn't develop boxers very well though. The Mayweather's improve fighters boxing skills but are focused on fighting in 1 way, they can't do so much for pressure fighters or fighters who fight small.
training with mayweather is only effective if you have the slick in you, if you're only an average fighter best go with roach or garcia.
