We (better) be losing Giles from the bullpen soon, but the usual vet signings and random reliever pitching well for a year, added to the 2 or 3 relievers we'll likely get from the starters who don't remain starters, will fill out the bullpen nicely.
Our outfield, and our cover infield (Urena, Drury and Valera = worst in the league) are bigger factors on limiting our win total IMO.
