First opportunity to talk about this trade without having to do it on an iPhone.
Personally, I think this works for both teams and is beneficial for both teams.
Columbus - Gaborik, though I like him, is done in NY. He's scored in 6 games this year, has blown all kinds of opportunities, and has been talked to ad nauseam by the coaching staff. That being said, I think he can flourish with the CBJ's by rejoining AA, Dubi, Prospal, and Tyutin. Good upside for the CBJ's and their scoring issues and a good possibility Gaborik regains some of whatever he's lost and start over. Sometimes, that's all you need, a fresh start. Sorry to see him go, but it was time.
NYR - Brassard is an asset to depth at Center (3rd center here, one would think, depending on which Brad Richards decides to show up) and can certainly add something to the 2nd PP unit. He's decent on the PP. Dorsett is a heart and soul guy that's a shade less than a guy like Brandon Prust. Too bad he's injured. Moore should immediately be the #4 guy as he's an upgrade over Gilroy, Hamrlik, Emminger, and Stralman. I immediately put him above any of those guys and once Staal is back, he's a decent option on the 5/6 pair and can move the puck and is remarkably speedy for a large guy.
Overall, this helps deficiencies in both teams. The Rangers needed an upgrade on D, needed help up the middle, and a little more sandpaper certainly couldn't hurt. The CBJ's get a top line RW and send a nice message to their fans that they're in it for real for the next two seasons.
Fair deal for both sides that helps both clubs.
