I look at Sandy's moves from a strategic standpoint. To evaluate the deals, we'll have to wait a few years to see if the long term result was worthwhile. If he had re-signed Murphy, it would have been for multiple years (let's say 4). Instead, he got Walker (who isn't exactly chopped liver) for one year, and it will open up the spot to play Dilson Hererra, most likely for the three years after this. But you also have to view the total salary difference over those four years(the difference between four years of Murphy versus one year of Walker and three years of Hererra). Several pitchers will be getting eligible for large contracts over that period, and the money saved can be spent to help keep the pitching. Later
