If this is the reason then count me in. If he has just lost his love for the game then that would worry me, as I would think his head wouldn't be in it even if he decided to play. Although Ryan O'Reilly said he lost his love for the game in Buffalo and a change of scenery worked out well for him.
I don't think there has been talk of Buff not getting on with teammates in the past, so it could be because of some specific incident that occurred in Winnipeg. It doesn't mean there would be issues on a new team.
