The Buffalo Sabres, after adding Raffi Torres, have traded Clarke MacArthur to the Atlanta Thrashers. MacArthur, 24, has 13 goals and 13 assists and is -14 in 60 games so far this season. His spot in Buffalo will be filled by Torres, and he'll try to fill the void left by Ilya Kovalchuck in Atlanta.
This dramatically increases the fantasy value of MacArthur, who will see more playing time and more shots in Atlanta. He is owned in less than two percent of ESPN leagues, so strongly consider adding MacArthur for the stretch run if you need a left wing.
