In no particular order
Sedins back to Vancouver- The Canucks added 160 points with these two guys at relatively cheap.
Koivu to Ducks-He adds a very strong 2nd line center that the Ducks have been lacking. When the Ducks pushed the eventual Western Conference Champions Detroit Red Wings to 7 games their 2nd line looked like this: Teemu Selanne, Drew Miller, Andrew Ebbett. Now that 2nd line with Koivu: Selanne, Joffrey Lupul, Koivu. The total of points for the Miller-Ebbett-Selanne? 96 points. The new line total? 154 points.
Beauchemin to Toronto-Big, Physical defensemen. Very Good slap shot. Solid Defensively and young for a good price.
Marian Hossa to Chicago-Talent wise this a great deal. It gives the Hawks a great top line. Toews-Kane-Hossa. But they gave him way to much money. 12 year deal? wat the hell? hes 30! i can see that for a younger guy like Zetterberg, even though its still a little much. He wont be out of this until he's 42!
