I could also see the Mets being in on JD if they actually want to make a push to the WC, since their offense and left side of the infield reeks. Philly could also be in on it if they don't trust Franco at 3B. Definitely the fact that ATL and PHI are surprising early opens up a few more suitors, and with the Dodgers falling out of the playoff picture, the NL is looking pretty open - I mean, if the season ended today, NONE of LAD, CHC, WAS, or ARI are a playoff team.
But yeah, I'd definitely be wary about giving 5/150 to JD. I'm assuming he'll bounce back from his little slump, but some numbers are getting concerning. Ks are up a bit, he's hitting more GB and less FB. No idea how stubborn he'd be, but odds are he'll still be better defensively than Vlad at 3B, so as long as JD is here, Vlad really isn't going to be getting much action on the corner there.
In a perfect world, you deal JD, and we sign Harper. We've got a clear need for a left handed middle of the lineup OF bat, but that only happens in video games. As mentioned, they really need to shore up the rotation, so ideally if you're looking to move JD and Travis, yeah, getting rotation arms are the way to go. The bigger problem is that the rotation is always really hard to fill in FA, and we just don't have the MLB-ready arms to step up. Really not sure what can be done there, and the problem is even worse if Stro and Sanchez don't return to form.
