I just got a subscription; not so much for fantasy football or betting, but I'm pretty intrigued from the whole advanced analytics angle. I've been mainly trying to find research on FAs, as well as look further into the CLE guard situations. After putting off the $27 commitment for a couple weeks, I finally pulled the trigger. It's got lots of cool premium shit, and I would say it is worth $2.25/month.
Not sure how huge of an undertaking it would be, but I'd LOVE to see a similar site with NCAA prospects.
