Both can play RD, but the only natural RHD on the roster is Demers. And Chayka/Tocchet have talked about the need for more "balance" in the lineup in terms of handedness.
Sorry. Can't help there.
Even if I agree to gut our RD as a short term measure, Shatty is not available, and we would not agree on DeAngelo, who if all other things are =, is more likely best for NY to continue to have his def develop. Then keep or flip for better value later.
Pionk has emerged, but I don't see a fit on what you have to offer and what we would want.
Pionk + is a discussion for EDM 10OA.
5th is too much for AZ, and not sure what we could add, other than Buchnevich and a 2nd, if I haven't moved him already.
