Buffalo is not mismanaged far from it. Murray doesn't have an easy job he has to clear all the mistakes from Regier. Sure Regier didn't have a lot to work with because their former owner has been a penny pincher who couldn't care less about the team. Burke once said about Regier that they spoke a different language in terms of judging talent in trades and that the guy was just too reluctant to give up anything worthwhile in a trade. After Pegula bought the team he saw first hand that Ruff, Regier and their current core (Vanek, Pomminville, Miller and Roy) aren't bringing them up the cup so they blew it up. That's not mismanaged that's looking forward.
McEichel will be the biggest piece of their puzzle but they already have some other young and coming guys on the team/minors and Buffalo isn't going to make the same mistake as Edmonton (a.) drafting offense after offense and b.) rushing them to the NHL when they aren't ready.
What other options does Buffalo have ? Other than teams like the Leafs they for sure weren't going to keep around a core that just couldn't get the job done so that means rebuild from top to bottom at that phase people can't expect UFAs willing to sign there. So the only logical step is to draft as good as possible and make no mistake Buffalo isn't the only team gearing up for one of the two phenoms and guess what their fans deserve it. I just have a bit of a soft spot for them because their story reminds so much of the Wings pre Yzerman and pre Ilitch.
