I got comped a copy of FanGraphs 2nd Opinion and they said if I liked it to please pimp it.
While I am quite skeptical of the stat-set's orthodoxy, the thing I was most excited over about this downloadable PDF was its lucidity and accessibility. You don't need a post-doctoral math degree to pore over numbers that split hairs - there is meat on the bone here just abut everywhere.
While it is far from Angels-centric, I am already marking crap up everywhere to help with my fantasy draft. If you are going to drop eight bucks on anything hardcore baseball related, I would say this is it.
