Not to be rude, but to think that a rebuilding franchise such as Seattle would have any interest in someone such as Ellsbury who is no longer cheap or under contract for more than a year and 2 months, is rather naive. For one of the best pitchers of our generation, Seattle will no doubt want at least two of our best young players who will be under contract for multiple years.
If you disagree, please point out the last time a pitcher of a similar caliber, who was still under contract for multiple years was dealt to a rebuilding team for anything less than 2 of the other team's two best young players.
