No disrespect to Billy Robinson, but Archie could shoot too. After his initial training in the dungeon in 1962, Stu Hart sent him to Kansas territory for additional training (hooking as it was called back then) under Pat O'Conner and Lou Thesz. By 1969, when Billy arrived in Stampede, Archie had already wrestled Pat O'Conner many times as well as Harley Race, Lou Thesz, Gene Kiniski, and Dory Funk Jr (the latter three for the NWA World Championship). And Archie could go sixty minutes all day long.
It's always tricky when discussing a wrestler's pro wrestling skills and then mixing in their shoot background. While a wrestler may be skilled in both, shoot fighting is the antithesis of pro wrestling which depends on trusting your opponent with your body while convincing the fans it is real. I understand that most of the members here cherish their old school British wrestlers and rightly so. Count me as a fan of Billy Robinson, Kendo Nagasaki, Les Thornton, Geoff Portz, and The Dynamite Kid. But to say Billy would have torn Archie to shreds is wishful thinking.
As regards the comment that Stu could not start a hold from standing position, age must be taken into account. By 1972, Stu was in his fifties and had arthritis and bad knees. So starting from a standing position was not really an option for Stu at that time.
