Olympic coverage

I have to admit that I like watching the Olympics, but some of the things the commentators say seem very strange or less than intelligent to me.
Like:
You get out front and you stay in front. That’s how to win. (Do people need to be told that?)
This is really hard unless you practice a lot. (You think?)
You guys at home are really excited about this. (How do they know?)

I wish there was some way just to watch the feed without them.
