That was an extremely well written article and made me realize how much i miss speaking, reading and writing in french (been out on the west coast for 7 years now...my vocabulary has eroded even though my hard earned Quebecois accent has not).
The best part of that article, which seemed directly applicable to the current situation with PK, was Denis' description of his relationship with Tortorella in Tampa Bay. As i understood (and maybe I'm a little off), he was saying he never got upset when Tortorella was harsh on him to the press, but that it took its toll when Torts would criticize his play then not give him the chance to make amends soon after. Basically that combination called his own abilities into question and made him doubt that he could be a starter in the NHL.
To those of us who follow the Habs more closely than we ought to, i think we probably worry that the same thing is happening to PK. Criticize him, reign him in, bench him when he messes up, sure...but maintain a balance while doing so. You want to ensure that PK understands there is still plenty he has left to learn, but that, at the end of the day, he still knows he has the confidence and support of his teammates and coaching staff.
