I don't think anyone is really pushing Phil out the door, just sorta discussing things.
Friedman listed Calgary as a potential landing spot for Phil, because of their need for offense from the wings. Hamilton makes a ton of sense because of our dire need to fix the blueline, his reported unhappiness or at the very least lack of a fit in Calgary, and the fact that he's exactly what we should be looking for in a blueliner. If the trade was centered around Phil for Hamilton, minor pieces added on either side to balance things out accordingly, would you pull the trigger? I love Phil, but that's a deal I'd probably make. It also makes moving Letang much more palatable, depending on the return he brings (which I'd imagine would be significant, warts and all).
I don't think anything big happens this summer, but I wouldn't be upset if JR tried to get ahead of a potentially huge problem by moving one or both of Phil and Letang. I think Phil's a more integral part of this team's success, as we live and die by our forward depth and production, but if he's been at odds with Sully for multiple seasons and it's not improving, it might be in our best interest to move him for a big return before A. the wheels fall off and his value subsequently drops, or B. Sully is fired and Phil's "coach killer" tag is made much worse, hampering his value.
