An odd source to report this, but I suppose it's newsworthy none the less; Phil Rogers of the Chicago Tribune did a piece on shortstops and included this line:
Jake will be the first to tell you the Chicago media is awful and I tend to think this report cannot be correct, it clearly wasn't the plan last year -- the team had Harris move to second base down the stretch for a reason -- and I'd rather acquire a defensive shortstop with Harris being the first guy off the bench rather than becoming the next Ty Wigginton and being overused in positions he has no business being in or at.

Some other links and notes:
A Cubs fan thinks the Rays - Cubs could hook up on a Cedeno + Hill for Crawford deal -- it would take more than that.
From Eli's MLB Rumors
I have no idea how credible the guy is, but he seems to have a load of interviews with baseball folk. Wilson (08:$6.5M, 09:$7.25M, 10:$8.4M club option ($0.6M buyout) is pretty expensive for a guy who's .790 OPS was the highest since 2004; he's got a good glove though.
