They're both free agents come this offseason, so it's not as if some big move will land those two on the north side. Naturally, both of them have been mentioned as targets for the Cubbies this winter, especially Furcal. I doubt they land both of them, but it'd seem like a given that they wind up with one since Sammy and Nomar will both be off the books in 2006.
Moreover, both would be great fits in Chicago and fill several of their needs. As much of an upgrade on all fronts as Burnitz has been over Sosa, I doubt he's brought back. It's seem like a natural fit for Giles to come in to fill that void, since the Cubs would be lacking any sort of power from the left side.
Furcal is going to be one of the more touted FA SS's this winter, but I like the Cubs' chance of getting him. They'd likely over him a good multi-year deal and he'd fill the gap at short, be that proven leadoff hitter they still need and provide some speed on the basepaths. I've soured a bit on the value of speed and stolen bases in recent months, but it's still not a bad thing to have a guy who gets on base regularly that can put the pressure on the pitcher because he may swipe a bag.
Of course, the Cubs are no strangers to shattering what seem to be the most logical of moves.
