My two cents.
From the outside, it seemed like a big rift between management and Kessel and from that point on, moving him was inevitable. Neither management (JR and Sully) nor Kessel seem like the type of dudes to genuinely go "all good, water under the bridge, lets do this". Again, based on my feeling from the outside.
Am I enthused by the return? Not at all. I think the most positive thing I can say about Galchenyuk is that he's UFA next summer and we can possibly clear his cap hit, and by extension, Kessel's cap hit. With that cap space, you can acquire someone you actually want. I understand that JR's hand was tied by Kessel's unwillingness (which is his right, no qualms about it) to move and that this might have been the only move available.
I don't necessarily think the Pens are worse off as a team, though. Kessel is a far better offensive player than Galchenyuk, but hopefully Galchenyuk comes in without the other stuff that, for better or worse, Kessel carries with him that rub some people the wrong way.
