If you'd included Dick Irvin Sr. in your primary list (as you should have young man) then yes, yes you could add to that list.... antecedents going back to Chicago & Toronto of the 30's, as a Player, the PCHA & the Patricks etc.... And while Toe Blake does top my list of the Greatest Coaches Of All Time... a very strong case can in fact be made for Irvin given what he had to work with coming in, turning things around in so dramatic a fashion, winning Cups. Extraordinary W/L Records. Montreal for example (dissecting the Leafs & Chicago as well, reasons to rank him very highly indeed), franchise was absolutely on the ropes when he joined in 1940, the ranks then being depleted by the War.
What he managed to pull off in the face of all these challenges nothing short of miraculous, laying the foundations which with the arrival of Frank Selke Sr following the War laid the tracks, foundations for what Toe Blake was comfortably & seamlessly able to step into.... all that followed right through the 70's. It is said that a Mans true character is displayed, can be measured in seeing how he deals with & responds to adversity. Dick Irvin Sr faced considerably more adversity than did Blake or Bowman, an interfering owner in Toronto who always thought himself the smartest man in the room & thus hobbling those around him, second guessing them... in Montreal, creatively dealing with constraints, seeing what he did in Maurice Richard & encouraging him, giving him the chance that no one else would, placing him on the Punch Line, Launch Pad... Houston, we have contact.... had the eye & mind to see what he did, confidence to run with the unorthodox in Bill Durnan who certainly didnt disappoint.....
So ya, Dick Irvin Sr. He'd be up there on my list, one of the most important & influential players & coaches of the early & mid 20th Century who's impact on the game & the lives he touched were profound, echoing long past the year of his death, 1957.
