I believe that it was a wise decision to re-sign Casilla.
He is a very talented right handed pitcher. He adjusted nicely to his role as closer (during the 2012 season) in the absence of Brian Wilson.
He did happen to go through a very long and grueling slump last summer, but he seemed to have regained his full form during the World Series.
Now that the Giants have re-signed Casilla, they basically have the exact same bullpen that they had throughout last season. With that thought in mind, they may be able to reclaim the World Series title again! I'm not saying it will definitely happen again, but they definitely have a shot at it!
The Giants have one of the strongest bullpen's in the league. The have pitchers like Romo and Lopez and Affeldt, who have the ability to overpower any hitter, whether they bat right or left handed. The strength and depth of this bullpen is something all Giants fans take pride, and it causes a lot of people to respect them, rather than overlook them.
