I would like to see an expanded offering of fantasy sports. I play fantasy football, basketball and baseball every year on yahoo, but I would love to see them offer true college football and college basketball fantasy game. (Not the stupid pick em games. That's boring.) I've seen other site do them (CBS sports did a fantasy college football one for a few years). The two sports are of course hugely popular.

I would also love to see a fantasy tennis offering. You do NASCAR and golf, and tennis is far more entertaining than either. Fantasytennistour.com offers a good one for some ideas for yahoo.
