Like BigBone said above, I think he's become more successful as a head trainer so he probably doesn't have time to be an assistant trainer anymore.
Now that Campbell is retired and Allen Green split with him, I guess his biggest name fighter now is Randall Bailey. He does work with a lot of local boxers though and even has a amateur team.
he was one bitter mofo i remember he came on a radio interview and was asked what his thoughts were on bhop beating pavlik, he went off on a rant saying he came up with the gameplan and had bernard practicing it until jazim decided to join the camp later and because bernards friends with nazim he got the position of head cornerman. he also said they used his gameplan for mosley vs margo.
