An interesting article about the "hockey handshake" tradition. One of the first things I needed to understand when I started watching baseball was the handshake thing.
At the end of a big hockey game, the teams shake hands with each other, that is each player shakes hands with each and every one of the opponents, and generally not with their own teammates at all. I was used to that and I see that as a "ok we were hitting each other, but no hard feelings."
But at the end of a big baseball game, the winning team shakes hands amongst themselves, that is each player shakes hands with roughly half of their team-mates (the ones on the field shake with the ones who were off the field) while the losing team disappears as fast as they can.
It's tempting to see this as a fundamental Canada/US dichotomy, but it's more a baseball/hockey thing and I suspect it's because hockey is a contact sport and baseball (at least on paper) is not. Forgiving the person who has bruised you and saying "good game" is probably a lot more important in contact sports. And indeed, it seems that football goes for the "shake the opponents hands" tradition.
I have to say I'm more the hockey handshake than the baseball handshake type, even though I'd rather watch baseball than hockey most of the time. I really like the idea of taking the time to reconnect with the opponent and affirm that you're really all part of a large thing (the league and the sport) and are colleagues in that effort. In the same way, everyone in this business is a colleague, even if we compete from time to time.
