That's all you need to know.
Okay... maybe not everything, but that's a ton of great info completely free. You can pick which projections you like, or an average of many of them. You can input your own league settings, which will impact the values of guys by a TON.
One thing to watch... try playing with the hitter/pitcher percentages to get some values close
to where you think pitchers in your league will go. I found that a 65/35 split still
had pitchers ranked way
too highly. I should have gone 70/30 or maybe even 75/25 to get the values closer to where my league valued the pitchers at.
I found that the values that were placed on star players were far
higher than those on the standard Yahoo list. For instance, based on this price-guide I would have been willing to pay $70 for Pujols. I suppose I can look at that two ways, when I picked him up for $48. Either I got a bunch of great values in guys in the top 30 (of which I think I have 4-5), or the price guide I was using valued them too highly. Then again, I'm more of a stars-n-scrubs guy anyway.
