Sports NZB index sites?

I've been searching for sports indexing sites, does anybody have a good source? Am looking for US college sports like football, basketball, etc.

Same as with your FLAC post really, search a team name I guess and see what comes up.

Remember if no group actually releases it, then there is not much hope, so you are maybe relying on a home made rip or capture and I guess they are more likely to be on a Web site.
