Of course it's also hard to compare cause Bylsma won a Stanley Cup his first year and because Crosby was a Bylsma backer (like it or not the best player in the league gets some say), so that was almost surely part of the reason for the overdone loyalty. He didn't have any problem canning Therien after a SCF appearance when they were on their way to crashing and burning the next year.
It's not as if there's any obvious guy to take over either if Hynes was canned, unless you're a believer in Kowalsky but I don't think they'd promote him until he started getting some notice around the league. Not to mention this team's still got a cap floor payroll and at best is a borderline playoff team anyway, I don't think Shero would do anything vis-a-vis Hynes unless the team really started quitting a la the Jets with Todd Bowles and/or the expectations of actually making the playoffs anytime soon finally got raised.
It is true that Bylsma won a Cup and that buys some leeway (as does repeated playoff appearances, in general). I wasn't really aware that Crosby was a Bylsma backer, but if that is the case, then you are right best player on the team (and in the league, by many people's estimations) does have big input, and that's not necessarily a bad thing, just reality of the situation. Things would be different with regard to Hynes, since so far Hynes has no Cup and no playoff experience.
Also true that he didn't have a problem canning Therrien after the SCF appearance. Perhaps that bodes well for him having a sense of when to pull the plug on a coach.
Just to be clear, my post wasn't so much saying it was time to pull the plug on Hynes (because I don't think it is, yet). Rather it was considering the question of whether Shero's potential to cling on to coaches to long might carry over from his time in Pittsburg, or if he had learned anything from the Bylsma saga. My hope would be that he learned from the Bylsma saga and moves onto the Devils a little wiser about the pitfalls of potentially being too loyal to a coach.
That being said, I don't really think it is time to fire Hynes, partly because I'm not sure there is a better option out there, and while there have been issues with our structure, system, and motivation as a team, we are also talking about a second-year NHL coach, so growing pains must be anticipated, and there are some other good things about Hynes (like that he is willing to use and develop young players, etc).
