who did stu train,you are kidding right,all his kids,bret,owenetc. jim nieinhartd,chris benoit,the british bulldogs,chris Jericho,the list is endless.
You may be surprised to learn that Stu did far less of the actual training than many people think.
Davey & Dynamite were both trained by Ted Betley in Lancashire before even coming to North America.
Benoit learned the basics in the "Dungeon," but earned his wrestling PhD while working in Japan.
Lance Storm & Chris Jericho were trained together by the Hart brothers. And again, both guys merely picked up the basics in Calgary while expanding their repertoire in promotions abroad.
As for the Hart boys, Hito and the Cuban Assassin conducted most of the lessons when Bret & his siblings were learning the ropes. Bret discusses that time at length in his (very lengthy)
You seldom hear any Dungeon graduates mention training with Stu. It sounds like he left the operation of his "school" and Stampede promotion largely in the hands of others. I get the impression that he sat in on some of the training sessions, but was nowhere near as actively involved as the public perception.
From what I've learned and observed over the years, the Harts are a lot of "talk."
