The overall job yes, game plan against Pacquiao...not so much.
The counter punching was not there, the boxing in the last 3 rounds only worked because Pacquiao slowed down, his punches were a little slower and became flat footed, and bigger periods of inactivity let Bradley steal the rounds off the jab. When he was trying to counter punch early in the fight Pacquiao's in and out movement was too quick for him.
I think too much emphasis is put on trainers anyway, they can only do so much. Diaz has done a good job with Bradley, this was a new level for them and both of them will probably be better for the experience.
But I refuse to acknowledge that he ever won that fight, not ever. I have watched the fight 3-4 times. That was enough.
