It's really just to get a "fresh" take on things, that's all.
Unfortunately, the real stupid thing is that the main parties are so enamored with themselves and so ego driven there is no way they're going to listen to a "neutral" 3rd party and come off their high perch to get a deal done. To them, it's "losing" as opposed to "negotiating" and neither Fehr nor Bettman are willing to do that.
I really hope I'm wrong though. Downtown St Paul is essentially a wasteland without hockey, and a lot of businesses have laid off countless staff members while this drags on (a few happen to be very good friends).
