Anyway, what about sports blogs, like Deadspin.com? I'm a faithful reader there and there's a big base of sports nuts that consistently visit it throughout the day (so I'd think they'd have to some time to kill each day here), and I can't imagine it costs too much to advertise on a blog, but what do I know. Might be worth a look.
