I know the founder of this site. Very interesting approach in terms of data collection and analysis. I won't go into much detail here but check it out. Jack, don't know if this goes against the rules but this site (last year was first year) was of *great* value to me last season. This is FREE, not a subscription site. I guess they make their $$ from clicks and advertisers. Anyway, wanted to pass it along:
