The difference is that they've got most of their team filled out with cheap, homegrown guys... Fielder, Weeks, Hardy, Braun, and Hart are all making league-minimum, IIRC. Not that spending money on the bullpen is a great investment, but they can afford to blow a bit of their cash on it since they aren't paying like we are for position players. Lee, Ramirez, Soriano, and Fukudome, Z, and Lilly alone is gonna cost us more than their entire team, most likely.
