Where do you think the handshake ritual came from? I've never researched it but, having a kid who's in college and still playing goal, I've always assumed that it's like boxing or gunslinging or the other old-school rough "sports," where "gentlemanly" rituals grew out of the basic need to separate the sport from the rest of life.
It's why I never bought into the "ban the Indian mascot" movement; in fact, I've publicly argued against it. Because it always seemed to me that the Indians well understood the inverse need for inherently peaceful people to go through a ritualistic preparation for war, sort of the "pep rally" before the game, if you will. So, far from mocking native Americans, making Indians sports mascots not only makes perfect sense but actually honors an aspect of their culture that we arguably don't do as well. It really has nothing to do with being "PC"; I reject the premise that it's derogatory in the first place.
Why do we play so rough here? Because a forum like this is as impersonal as flying drones. We don't sit around the table and debate these things, so we tend to forget our manners.
And, yeah, Leighton looks good between the pipes. The can of whoopass the Flyers broke out on the Rangers night before last was a delight to behold. I followed the Flyers in the days when Bernard Marcel Parent was in goal, so, for me especially, they just aren't the Flyers without great goaltending. Sadly, it's been elusive for them for quite some time.
