The Cubs have already been pretty active, shipping Jones to Detroit for Infante (and salary help) and Monroe to the Twins for PTBNL. they're switching Dempster to the rotation (thank you, God!), and are apparently packaging a deal to try to get Carl Crawford (Hill + Marmol enough? if not, some deal including Pie, or Cedeno). they're also rumored to be making a run at Fukodome and a couple of Japanese pitchers. if they start Dempster and trade Marmol, i'm sure they'll go after some closer. maybe not Cordero, but perhaps a trade for Fuentes or something.
i've gotta hand it to them. they aren't content with a team that was probably the best in the NL from June till the end of the season. they're upping the ante for the rest of the division as well. the way they are building the team, the Cards will have a difficult time contending in '09 or '10 either, much less '08.
