Not even close!! Floyd joy sinclair who was trained by Floyd joy sinclair Sr damn near shut out and almost knocked out Manny pacroid who was Freddie's best fighter!!
Joe Frazier, Larry Holmes, Riddick Bowe. The main thing here is that all of them have completely different styles
I don't know if he deserves the distinction of being the best (albeit he's definitely one of the best) but Manny Steward is my favourite one.
Booth has a great understanding of a fighter's individual needs. Every fighter he has handled has been a champion at one level or other. Those that have left him never reach the same levels. George Groves is a perfect example.
