You can go back and look at all the ED threads. Poms could've been bought out, or, Fletcher could've been more farsighted and made moves much, much earlier. It was pretty obvious to me and some others that Pominville was declining long before( I thought he showed signs of decline in the CO series), and that Scandella was a third wheel on the middle pairing. Trade them for a decent return back when they were tradable, rather than wait till you have no other choice but to make a desperate and poor deal. Even better, don't give aging players like Pominville NMC's in the first place. This was a mess of Fletcher's making. GM's knew the ED was coming, but Fletcher took no action to protect the team from the consequences.
I like some of what Fletcher has done, but he has been timid and indecisive at times, which has left this team in the position of being perennially mediocre.
