Dude was training with Khan, there is a picture of the two on his twitter, and the next day he switches trainer. I don't know about you guys, but I find that extremely odd. Even prior to that, two days before, he tweeted, "Can't wait to train with the A team, on my way to the bay area".
How is Virgil Hunter over-rated? He turned Khan into a way different fighter when he fought Collazo. That is something Freddie Roach could not do, and Roach is considered one of the best trainers. And please don't bring up that he looked bad against Collazo because the learning process takes time. When ever you are learning something new, it takes time to kick in, and only through repetition of drills, does it finally show.
According to his interview, he said it was nothing personal, he just prefers being closer to home and that nhis opriginal trainer suited his style a little more
