Just because it happened frequently does not make it reasonable or any less of a problem.
If you don't think the insane amount of intimidation the Russian military and police put on the team had an effect on them I suggest you do some research. I'm sorry, but no matter how you cut it, being in that setting, which the fear of being taken by the military or KGB, or some other organization you've never heard of and executed or shipped to Siberia WAS a concern MANY of the Canadian players had. Many of the players acknowledge that the intimidation factor severely effected them.
I've done an enormous amount of academic research on the Summit Series. In the DVD series, if my memory is precise, about 5-8 of the Canadian players directly discuss the role of intimidation (on and off the ice) in the series. In the collectors card (20th Anniversary, I forgot who produced them, it was not a mainstream hockey card company, however), set, which included typically a quotation from both the player and then usually a media quote about the series and the player, an additional number (I believe it was 3-5) identify the same thing as an issue and a problem they faced.
I'm not trying to say that the Soviet Union was dirtier in the series. Far from it. I'm saying that BOTH teams partook in different types of illicit behaviour. Just because it wasn't as obvious as Clarke's travesty does not mean it was not there.
