What would be your recommendation for a site that covers all (well, at least a respectable number of the more important) sports reasonably well?
I like NBC sports. I think their NFL football coverage is the best. They also don’t have as many videos as most other sites.
ESPN is annoying with all their videos. CNNSI is also good, but the website tends to launch multiple windows.
TSN is great for the NHL.
I like CNNSI the best. ESPN has some good content here and there, but the site is a busy mess and all the video is annoying.
FWIW, I have ESPN bookmarked. but all I generally want are scores, headlines, and sometimes a deeper look at the SF Giants. I watch a lot of Sportscenter on TV. I’m perfectly satisfied as far as my internet needs go.

If you watch a lot of Sportscenter, you won’t learn anything about the Giants. The only baseball teams they’re allowed to cover are the Yankees and the Red Sox! 
That’s why I hit the website.

I read both ESPN and Yahoo!. ESPN is almost certainly better overall, but I try to avoid feeding their giant hype machine so I read other sites as well.
