With regards to Orr's attempted comeback with the Hawks after 20 months off trying to recoup: Read more: http://sportsillustrated.asia/vault/article/magazine/MAG1094168/2/index.htm#ixzz1GG7AuAfC I knew that the real oldtimers played entire games. And I knew that pre-expansion guys played very long shifts and a lot of minutes (even star forwards did) compared to today. I was a bit interested in Orr's icetime because as a defenseman that could skate as he could, and with him being such a physical specimen for his time, I felt he was most likely capable of playing an awful lot even in the 70s. I have brought this up before a couple of times and got the "around 30 minutes a game using estimates" dismissal.. but I have seen a few references to Orr averaging 40 minutes a night as I have been researching for the ATD. Curious what you guys think about this because obviously it will affect a lot of the analysis that is done. Has anyone come across any stated icetimes for other clear #1 defensemen of the time such as Park in their reading?
