It is my tendency in any sport, when my own team(s) drop out, to root for the team that has had the longest wait for a championship. Thus I rooted for the Hawks in '10, the Canucks in '11 (they had never won -- and still haven't), and the Kings last year.
I was in a bit of a conundrum this year because the NHL's final four teams were the previous four champions ... none of the teams had waited long since their last Cup. I took to rooting against Chicago more than anything since they had knocked my Wings out. But I try to be gracious in defeat ... so congratulations once again Blackhawks!
