Ya gotta like young pitchers like Vargas who can strike people out and post good ratios even with some wildness. Lots of upside if he can tighten up his pitches a bit more. As an added bonus, he pitches in the NL, in a good pitchers park, on a team with good defense, and should get good run support from MCab, Delgado & Co.
I've gotten very nice production from Vargas and Ervin Santana, both of which I picked up the FA list.
Meanwhile, many of the starters I drafted pretty high (Pavano, Odalis, Thomson, Pineiro, etc.) have given me nothing but grief.

I am the Master. Don't question the Master. Just do what he says and be proud.
