Without knowing league size or settings it's hard to say. Assuming a 12 team H2H with standard cats, your OF is pretty shaky and your pitching drops off pretty fast. Both Peavy and Vasquez are moving from the NL to the AL and both are moving into hitter's parks. I'd be pretty uncomfortable owning Vasquez this year where he's generally drafted. Peavy I'm a little more comfortable with but the league switch and park factor is no joke... check out Peavy's home/away splits at Petco.
You drafted a lot of really solid, no-upside guys. By no upside I mean the players you drafted aren't going to break out...the best you hope for is an "as-expected." People can go crazy with the high risk/high reward guys, and that's no good either, but generally you want to draft a few guys who are poised to break out because the name of the game is value. What you see is what you get with Joe Saunders, whereas a guy like Madison Bumgarner could be anywhere from terrible to great. That's the kind of guy you need a few of - championships are won on the back of high-upside, midround picks who pan out.
