This is probably a good time to bring up that the Cubs have a LOT of money freed up after this season. In starting pitchers alone(Arrieta, Lackey, Anderson) it's 35 million, plus Montero's 14 million, and upwards of 25 million in relievers(Davis, Uehara, Duensing, probably Rondon). The relievers will mostly need legit replacements, but given that there isn't much worth spending on in free agency, taking on a high dollar short term deal like Verlander's would potentially fit really well if it means the player cost is minimal. The complicating factor is that depending on how the calculation is done, adding Verlander might push the Cubs over the luxury tax, which is a non-trivial problem in the new CBA.
