I think in a keeper league that size, he should be taken way earlier.
I still don't think he will be as lights out in 06 as people are predicting. He also had some injury issues (alhtough minor) in 05. In terms of prospects, I have Liriano ranked slightly ahead of Felix right now. You can get Liriano much later and his upside is just as high due to the fact that he is a hard throwing lefty with pinpoint control on all three of his main pitches.
