In response to Not-A-Shot's comment:
You say that "not resting Chara was a mistake". I say, "Zdeno Chara is a professional. He wouldn't let pride get in his way of success."
Do you really think he bobbled the puck because he didn't take a game off the week before? Do you really think he wouldn't have deflected a puck behind his own goalie if he had watched a game from the press box?
Stop looking for perfection. Stop setting yourself up for the "I knew it" and/or the "I told you so". Stop buffering against disappointment if they should lose. It's pathetic.
Yes, I am suggesting that Chara may have played too many minutes in too many nights and it is affecting his play.
I suppose maybe I am saying this for all of the reasons you mention above... after all, you know me better than I do.
