Freddie addressed it in the first episode. He said Moorer didn't quite mix. He had an attitude problem so Roach fired him. He said Michael was a pro about it and said he hoped he could work with Freddie again and Freddie said the same thing.

It did seem like a nice changing of the guard thing. I can easily see Freddie unable to coach in the next 2 years and Manny could still be on top of the heap. If I were Pac I'd be grooming his replacement. I don't think Manny is that smart, tho.
