Pay structure should include a free 10 day trial. That way users will be able to see what kind of advanced stats and analysis that is provided. Through the free trial method, users will get a small sample of the site and develop a dependency of sorts on the site's analysis and find themselves needing it for the rest of the season!

There appears to be a lack of advertising on the site as well. Seeing that you work for Google, I'm assuming its not because AdSense wouldn't accept the request for ads, but a strategic move on your part. Nice job, it looks very clean and easy to trust. Having no ads at this phase in the site's development is a smart move, and as the site gets more web traffic it might be a smart idea to reevaluate.
