Was Emanuel Steward a guy who train..

He trained two time champ Gaby Canizales(Orlando's bro) who was a banger and many other styles. He seems best suited training fighters to work off the jab so his success with tall fighters is well known. But the list of fighters he brought up from the amateurs with the Kronk gym is amazing.

A good trainer is a good trainer, no matter the style...

hes trained holyfield and de la hoya and they dont fit that description, so the answer is no. he trains all body types.
