I don't think so. I think he knows how to play amongst men and that he's developing just fine in his role. He thrives on challenges IMO, so being at the NHL level has been good for him. Increased experience and we'll see quick returns. Also remember that Spezza was supposed to take on a "save the franchise" role. I think in his case, JM's mandate for him was great. Of course Murray benefitted from it and JM got blamed.
The unfortunate reality for the Habs is that this lockout is perhaps good for us. I'd argue more of our best players on our team are young and not yet into their primes so a lockout only gets them further to their prime. Some may think that it will screw their development which could be true but if they play in good substitute leagues perhaps it will be sufficient. Obviously, everyone would prefer them playing but the Habs' future looks better than its present so we emerge from a lockout stronger i think.
