I'm in a similar league to the one you describe. As a reluctant fantasy baseball player, I'm finding that I'm suprisingly excited by the impending draft. The scoring is straight forward, which allows me to evaluate players accurately even though I haven't been following baseball closely for 10 years or so. To me, that's the beauty of this kind of scoring set - it makes reasearching and understanding the value of players easier for people like me.
Oh, and coincidently, my league also drafts this Sunday. Do you mind forwarding along this "top preformers" spreadsheet that you speak of? I can use all the help I can get.
