EDIT: I should expound, lest I come off as someone simply making personal attacks. Who among us hasn't run into a spell of trouble in our personal life, be it substances, finances, infidelity, resentment, jealousy... If you want to take Yzerman or Sakic first, fine, but I don't think that was the point of this thread by a long shot. Mac ran into troubles like the rest of us, conquered them, and has provided us with many years of entertaining hockey before and since. To condemn him for his personal troubles has your glass house trembling in fear.
You are wrong and this is why. If I take my personal life to work I run the risk of losing my job because like 99% of the population we aren't allowed to take our personal lives to work with us. Lets not grant every althete with a sobriety problem sainthood just because it makes them seem more real to us. Hey, Michael Vick has paid he debt to society too and I don't see everyone jumping to his aid now that he is officially reformed.
