Its not about sure things. Its about having that dependable set up man to get you to the closer. For the past 3 years, at least for the most part Marmol has been that guy. Now hes the closer, and while I dont mind a lot of the guys we have as middle relievers or mop up men, theres not a one Id trust to consistantly take a 1-2 run lead from the 8th to the 9th. I dont mind Grabow despite his foolish contract, which is hardly his fault but hes not that guy. Marshall or Silva? I dont think so either. There more long men if your starter burns out early. Then theres the pool of Stevens, Gaub, Berg, Samardzjia, Parisi, Caridad and maybe even Cashner. Granted, I wouldnt be surprised if at least one of these guys gave us a pleasant surprise as Marmol did in '07, but Id feel more comfortable with another vet, and at something like 1.5 mil, Calero would have been a nice gamble. Waste of money. Why spend so much more gambling on a player when you can do it for much cheaper using someone already in the system? I'll never understand why some people are so quick to dump money on the most unreliable roles in baseball.
