Freddie Roach is not a good trainer at all

How the hell did he lost twice when his fighter has the biggest advantage? Shaq vs Oscar Dela Hoya, Oscar Dela Hoya was as drained as a raisin and he still whoop the shiet outta Shaq who had height/weight/reach advantage. NOW he trained Shaq for a fight against Shane Mosley, as you see in the show Shaq/Roach had all the agreements he picked the ring size/glove and how many rounds of the fight. YET HE LOST again. Freddie Roach is no good trainer at all. Mayweather Jr. beat the **** outta the BIG SHOW and theres no such thing as trainers. That explains a lot. My case is closed.
