It appears to me that players took less 'liberties' in the day when they were allowed to police themselves, when there was the fear of retaliation from a teammate. I understand that players are bigger, faster, stronger than they were years before, but it seems to me the major injuries were a lot less back in the day than now. Why, I can't say for sure but the league has not done a very good job of controlling these things (and Shanahan less so). There is no consistancy in the application and it just gets worse. I long for the old days, that's all.
