Fighters who have succesfully changed trainers

[General Zod]

I was debating with a Pavlik fan saying that Pavlik needs to drop Jack Leow and he said to me that," a lot of fighters have gone down hill after changing trainers." Can anyone here give any info on fighters who have done it successfully and those who have not done it successfully?

James Toney:
After firing Bill Miller he drifted into limbo for a number of years, until he teamed up with Freddie Roach. On a side note that working relationship fell apart though, due to Toneys lack of dedication to training

Lennox Lewis:
Forgot who his origianal trainer was, but most of his success came when he hooked up with Manny

Wlad hooked up with Manny steward and they are successful together.

That was one of his best decisions. Sdunek is an excellent conditioning coach, but as a boxing trainer he is very below average.

[BoxerDood]

Hopkins and Mosley teamed up with Brother Naazim and that was successful.

Mosley trained with his father I believe, who was in Mosleys corner when he fought Mayorga?

His game plan for the Margarito fight was inspired as well

Amir Khan;
He has obviously improved now that his hooked up with Roach

I do think that Katsidis should leave his trainer as well
