Wainwright is my top pick easily. I like Anderson's talent, but injuries scare me off a bit; if you can afford to account for DL time, then take him. After that, you could gamble on Haren in the NL again, or take Milone and hope he has a nice sophomore season. Kennedy is an option, too, because he's better than his surface stats from 2012.
If forced to choose, for long-term I go Wainwright, Anderson, Milone. For win-now I might go for Wainwright, Kennedy, Haren.
Everyone seems to agree on Wainwright, as do I. Anderson is an injury risk but his cealing is higher than everyone else on this list so that's 2. As for the third slot: Erasmo is a sleeper not a keeper. Tillman is a late round pick, and same with Hudson if you have the extra DL slot to stash him on. Hammel had a great year, but it's hard to trust a 30 year old pitcher who just had his first good year. I'd draft him, but not keep him. As a Milone owner I loved the games he pitched at home, but that only makes him half a pitcher. His low K rate also drops him down the boards some. Just like Hammel I'd draft him but not keep him.
The third slot is between Kennedy or Haren. Kennedy's K's were there and he did get 15 wins dispite an era over 4 and a rather high whip. He's a workhorse and capable of more. Some dismiss Haren because of the back issue, but he is less of an injury than Anderson as last year was the first time in 8 years he had under 200 innings. A healthy Haren can deliver an era under 3.5 and 200 strikeouts. I would personally roll with Haren, but if you are afraid he is hiding or downplaying his back injury the safe choice is Kennedy.
I agree with the others on Wainwright and Anderson, but I think I would go with Kennedy over Haren. You already have some pretty substantial risk with both of the first 2 guys. Waino could be back to his Cy Young days, but he might not. The risk with Anderson is fairly obvious. Since the safe pick also has some pretty decent upside, that is how I would roll.
It seems obvious the three runners for the two final spots are Anderson, Kennedy and Haren. I really like Haren in Washington. I think I'm taking Kennedy over Anderson, but I could be persuaded to the opposite. I'd probably be benching Anderson for every start against the Angels and most road starts against the Rangers. Kennedy seems safer to me.
