The issue with Buffalo and most of the other teams in a perpetual rebuild is that they don't have an identity to build around. That's the first step any team needs to take, and then they need to make moves to reinforce that. Remember, Shero mentioned "run-and-gun" when he took over from Lou, and Fitz followed that up by stating he wanted to build around Hischier and Jack Hughes. Obviously, Shero had flaws in his roster building, but Fitz has been doing a much better job, and he's been able to tinker around the edges when he needed to (see this season by wanting better goaltending and more skilled toughness).
Can anyone here tell me what the Sabres are supposed to be? The Ducks? The Sens? What is the "Yzerplan" besides just a buzzword? For God's sake, the Sharks have been more impressive than all of those teams. They've bought in to something over there and it shows. None of those other teams are anything other than a collection of mostly young talent.
