As I have stated overall I think CJ is a very good coach, but you hit on one of several things that do concern me. Then again I would probably find things that concern me with any coach.
However, the lack of urgency or emotional play, I may be wrong, but I believe the team for years has been instructed, trained, taught, whatever - to keep their emotions in check, under control. When Claude first got here the team use to take a number of retaliation penalties, especially against Montreal. I believe they have been taught not to respond as often and turn away from all the crap and let the refs and league discipline offenders. Just keep your emotions under control play the system, just play your game, don't get caught up in all the other stuff. A lot of that has to do with changes in the league but I also believe they have been instructed not to take (retaliation) unnecessary penalties. So they play the game not getting too high or getting too low just even keel.
Don't get me wrong, there is much to be said for playing a controlled game you want to keep your best players on the ice not in the box, but there is also a time and a place to play with emotion. After all hockey is an emotional game.
Case in point - finals against Vancouver there was the hit on Horton and Recchi sticking his finger in Burrows face and all the Bruins feeding on that emotion. CJ scolded the team afterwards for antagonizing with the finger sticking, but I believe it was that emotion and anger that enabled Boston to raise the level of their game and go on and win the series. Yes, much easier to do in a seven game series than through 82 games.
It is a fine line as you don't want your team to take stupid penalties, but you also want them to play with emotion and creativity. CJ is very strict as to what he expects and will allow to take place on the ice and the players know it. It's all about staying controlled and staying within the system. I believe that is why it appears so often that the players seem to lack urgency. I believe they believe they are trying and playing with emotion/urgency they've just been taught to control it.
I don't know, just my ramblings.
