Emmanuel Steward is very good, he's trained so many world champions (the most ever I think). He trained guys from scratch eg Tommy Hearns, and he can take over guys and turn them into much better fighters eg Klitschko and Lewis. One of the best ever.
Another underated trainer is Nacho Beristain, he trained both Marquez brothers and a few other champions (can't remember who), he's a horrible manager though. In the corner he's very calm and collected and is one of the best
