Is it possible that Felix Hernandez would be traded this off season?

Is it possible? Sure. The Mariners aren't going anywhere for the next 5-10 years so they might as well trade the star players on the team to a contender and start rebuilding over completely like the Pirates and Athletics did. If King Felix does get traded, teams that could use an elite pitcher of King Felix's caliber like the Mets, Twins, Tigers, Marlins, Rockies or Dodgers should make a move for him. The Red Sox and Yankees don't really need him since the Red Sox have Beckett, Lester, Lackey and Buchholz while the Yankees have Sabathia, Pettitte, Hughes and soon-to-be-Yankee Cliff Lee.
