No, most likely as simple as the Cubs are asking for too much in return and nobody wants to pay it. From what I've been seeing, the deal is already in progress. I can't imagine they'd be back and forthing this long while we play a man short. To be clear, I'm not talking blockbuster. Guys Villanueva and Schierholtz who have no business taking innings or ABs from younger options. They might not have a ton of value, but for teams in a pennant race looking to fill a spot, it could up the return from a pair of raw, hard throwing A/A- relievers to a pair of slightly less raw, slightly higher ceiling, somewhat harder throwing A/A- relievers.
