Murray inherited a roster that was on its last legs after a very long sustained run of excellence. Unfortunately, Muckler left the cupboards BARE. Basically empty. Murray perhaps should have re-built earlier but I think he's done a good job filling the roster with talent. We lack depth but that would appear to be for 2 reasons:
1. Budget
2. Our re-build is still new, some of our prospects are just cracking the lineup while others aren't ready yet to fill depth roles.
He wasn't a fantastic GM, but I think he did a pretty decent job considering the hand he was dealt. He did get us Karlsson, Stone, Hoffman, Ceci, Zibby, Pageau & Smith from the draft and Methot, Anderson & Turris from trades of drafted players. That's not a bad nucleus to work with. We're really only one or two good pieces away from being in the thick of it. That plus coaching improvements, an improvement in special teams alone makes us a playoff team again.
Also, systems are cyclical - ours is 24th because we just graduated a bunch of players because we need them on the roster both for financial reasons and because we succeeded in picking good players.
