Why is it that you see them willing to trade for an impact player (and thus give up, presumably, significant minor league asset(s)) but you can't see them signing a free agent that they'd have to give up the #11 (or lower) pick in the draft for or something? Salary-related. The traded for guy presumably would be making less money than the FA, plus they'd be younger as well. I don't know. If it were a TOR pitcher (such as the oft rumored David Price), I think the intention would be to immediately sign them to an extension, for at least near market value. Also, trading for an impact player would likely take at least 2 of the Cubs' top prospects, whereas signing a FA, even one with a QO, would only cost one potential top prospect. I do think that a deal involving impact talent coming in and multiple prospects going out is a near certainty in the next year or two, but I don't think that precludes a big ticket signing.
