Under normal circumstances, I would usually advise against keeping many pitchers, but with your list, I think keeping both Johan and Greinke would be the way to go. With only 40 players being kept, you can focus on offense early and have many great options. You would have to figure both of these pitchers would be gone during the first round of your upcoming draft. I just don't see any of the others being what amounts to 3rd or 4rth round picks in a 10 teamer.
It's going to be a tough choice for me. It seems you guys are in favor of me going pitching, which goes against my usual draft philosophy of going all offense early. Maybe this season I'll experiment with taking more pitching in the early rounds. Last season I lucked out and had Santana, Carpenter, Halladay(trade), and Greinke on my team, which was a nice windfall considering I was mainly focused on drafting bats.
Is trading keepers allowed? Generally speaking, I like keeping offensive weapons for keepers, more than arms. However, I agree w/ everyone else that Greinke and Santana are the best keepers of the rest.
However, could you move Greinke and/or Santana to someone to get a really nice bat? Maybe someone out there has only one really solid keeper and is willing to give him up for the two of your guys. Then you could keep Votto or someone else from your list and have a nicely upgraded roster.
Don't get me wrong, I like both santana & greinke, but they are both riskier propositions than say a Ryan Howard or David Wright for the long term.
With OPS as an additional cat. I would absolutley not let Votto go. He was a beast last year across the board (when he was not on the dl). I'm not one to keep pitchers so I'd go with Hill as your other keeper. 10 team leagues are loaded with pitching, don't keep a pitcher with such a limited amount of keepers.
I have questions about Hill. He had an outstanding 2009, but historically he hasn't been a power hitter - in 1720 previous major league at bats (about the equivalent of 3 full seasons) he hit a total of 28 HRs. Same in the minors. He's always hit for average, but me personally, I wouldn't draft him in the 3rd/4th round (where he's being projected), not if Roberts, Cano, Phillips, Zobrist (maybe even Beckham) could be taken later. Hill went 103-36-108-6-.829 OPS but a Dan Uggla went 84-31-90-2-.813 and he'll go probably 6 rounds later. Maybe I'll miss out on getting in on the ground floor, but I'd like to see Hill do it again.
Greinke and Votto.
