Player from an old team with a long rivalry against an opponent that his new team just beat in the Final made a statement that caters to making fans in both markets happy.
Nothing really too out of the ordinary here. If the Bruins lost in the Final to a team and an ex-Hab on the team made a similar comment, nobody'd be surprised there either. Or if an ex-Blues player beat Chicago, or if an ex-Ducks player beat LA, etc., etc.
It was a fairly empty statement and just got fans in the old market to do a gentle clap for it.
