I dont want to get off on a tangent, but I didn't hold the signing against him because to me it was pretty clear he wasn't so much wanting to leave Nashville but rather he(and/or his agent) were determined to get him the absolute max amount of money they could, and with nobody knowing for sure what Nashvilles budget really was, nor what the new CBA was going to allow, the only way to know what the market would pay for a restricted free agent was to seek out and sign an offer sheet.
If we aren't going to fault Poile for using the CBA to the clubs advantage (playing him less than 40 games his first year, choosing team requested arbitration the previous year, and subsequently denying his request for a no trade clause) then we really can't blame Shea for using the CBA to his own advantage.
