I didn't seriously mean to suggest that Price is playing to get the GM fired. The tricky thing is that, because his only other extended period of suckage in recent years did indeed occur when he was revolting against his superiors (Therrien), there *is* that possibility. I'd rate it as maybe a 10% chance. And incidentally, it is possible to be committed to a city and even an organization while concluding that the team's management is garbage and needs to go. Every fan on this site who hates Bergevin is proof of that. So Price's contract does not automatically conflate to an endorsement of MB/CJ. IMHO. Price has been committed to Montreal through ups and downs ever since he first arrived, and may have been willing to lock in while still reserving judgement on Bergevin, or still being prepared to give up on MB based on what he did or didn't do during the summer.
It's probably more likely that he is shocked and confused at the calbre of the defence in front of him, and not reacting well. Like some commentators, he may have expected the D to be better than it's actually turning out to be. This might explain some of the body language and the weirdly drawn out nature of his slump. (Usually Price's dips in performance are nowhere near this bad, and only last for 3-4 games).
Of course the most likely explanation is just that he's lost confidence. The thing with this is that Price is such a superior goaltender that the thought of him suddenly getting the 'yips' and losing his mojo seems rather unbelievable, a bit like Connor McDavid suddenly forgetting how to make plays at speed. When we explore other explanations besides this one, we're basically paying him a supreme compliment - i.e., that he's so good, he's above serious slumps of this kind, and that such a slump requires a special cause.
