Cotto has been helped by Manny. Andy Lee is ok with Manny, 1 loss which he's been ready to avenge for a long time. I think Dawson can get help from Manny.

Honestly for Williams I think his best bet for a different trainer to help him out would have been someone like Ronnie Shields or Pat Burns, not "super" trainers but good guys that know their stuff and could help with fundamentals.
