K, tonnes of moves recently. I have to comment on some of them:
The acquisition of Eric Brewer by the Lightning was a brilliant move; they are probably a top three team in the East now along with Philadelphia and Boston, although I still think Philadelphia is way too damn good not to make it to the Stanley Cup Finals, but I can definitely see the Lightning making an appearance in the Eastern Conference Finals.
The acquisition of Tomáš Kaberle by the Bruins was a good move; they're still not nearly as deep as Philadelphia, but seeing Kaberle set up Chara for one-timers on the powerplay against Ottawa was something to behold and will probably be a lethal combination for the Bruins. (And Toronto got something good out of the deal, for once).
The trade sending Erik Johnson and Jay McClement to Colorado for Chris Stewart and Kevin Shattenkirk was really surprising to me. Johnson was the Blues' #1 overall pick and is a great defensive defenceman with a bright future. Chris Stewart is a great forward, but the Blues are stacked with great young forwards, so I don't see why they would trade away a really great defenceman like that, especially after having traded away Brewer.
Blake Wheeler and Mark Stuart from Boston to Atlanta for Rich Peverley and Boris Valábik seems like a wash, to me.
Ian White to the Sharks is irrelevant. That team is not going to win a Cup.
The dumbest move I've seen so far has been Colorado sending Craig Anderson to Ottawa for Brian Elliott. Both goaltenders are slumping, sure, but Anderson is awesome and Elliott is awful. Elliott has always been awful. Anderson, for good measure, recorded a 47-save shutout (that went to the shootout) against the Maple Leafs yesterday in his first game with the Sens.
One final note, Sheldon Souray was placed on re-entry waivers by the Oilers yesterday. I doubt he will be picked up (although I hope that he is); the Oilers are just trying to get rid of him. He hasn't been very good with the Hershey Bears in the AHL and there are some major question marks surrounding his skating ability. Hopefully a team looking for a final push heading into the postseason takes a bite and claims him, but I doubt it.
