There's really no ideal scenario at this point. As long as it isn't Hudon, and to a lesser extent DLR, I won't mind much. We're thin at center, so losing Plekanec hurts, believe it or not. We're thin on LD too, so losing either of Emelin or Davidson would hurt as well.
Got a feeling Emelin is getting picked and Habs are replacing him by trading for Marco Scandella (not by including Galchenyuk either).
