Didn't see the air rifles Flatbutt,

I don't mind Bob Costas - I've always thought he did a pretty good job and am glad he is doing most of the announcing.
One thing I always look for is during post-event interviews for the winner to start off saying their opponent was tough and gave them a good match. That's sportsmanship. I realize many of these athletes get caught up in the moment - heck I would too. But sportsmanship really should be a routine for any athlete and/or team in any sport in any venue. Especially on the world stage it's a chance to represent your country in a positive light.
