That really depends on a lot of things. For example, will CQ's return continually be pushed back until the idea of him coming back this season vanishes? If so, along with the Sox having a record that could be in contention, yes I could see them going for him. One thing Kenny seems to show is that he wants this team to be a competitive team no matter what. Unfortunately given the way the last few weeks have been, it is more unlikely that we will trade for him because there's no point in sacrificing your future for an expensive player when that player cannot get you to the playoffs at that point in the season.
Always possible, but not likely.
