At the STH's Town Hall they were asked if there was a chance that they'd sign him... and Hexy, flat out and said he was not in their plans -- he didn't look real comfortable having to say it, but like Homer at GM before him, he did'nt sidestep or dodge any questions... and give the appearance of being honest.
My personal opinion is that Hall was the best bang for the buck as he killed Penalties well and was a good defensive specialist when needed, and won his share of face-offs... all at a minimum type salary and could be buried with no penalty. All that said, he was not picked up by another NHL team, so it is possible that they noticed that he did in deed lose a step in the NHL. I believe that with Umberger coming onboard, Hall's PK and possibly defensive specialty role will be taken over by him... of course, besides the PKing, his spot on wing will determine his flexibility... and Hall's spot is now open for a kid/prospect with Hall's duties being taken over by others.
I don't know how well he will do in Switzerland, but I imagine he will work his arse and do as much as his limited abilities and age allows him... IMO he was liked by the fans and I believe by his teammates, even if no other NHL GM believed he could still bring a lot of role playing to the table for such a dirt cheap price... I wish him well.
