I just hope we don't trade Caleb Jones or Ethan Bear for some borderline #4 Dman, because we would greatly regret that in the long run. Ethan Bear at the very least will be a 3rd pairing Dman who is absolutely LETHAL on the PP -- and that's at the VERY least, mark my words (outscoring a blue-chip prospect forward like Barzal in the CHL playoffs is no small feat -- even more so as a Dmen, and they're the same age). I think Caleb will be like left-sided Petry: good at everything, but not dominant in anything; still very useful, though, and we need to keep him. I'm not sold on Nurse yet at all. Just my opinion, but I'm usually not too wrong about Dmen. Forwards is different, but Dmen I can usually get a good read on.
I would rather just sign Franson, as I think the cost for any reasonably good Dman would be too high.
