Even if they're right and we can't keep Greinke, I'd consider arbitration worth it for Greinke and Marcum....if they sign elsewhere, that's likely 4 draft picks with potentially higher ceilings than the prospects we'd trade for would have. The only free agent to worry about leaving without compensation is K-Rod. As for Aoki, he's deserving the chance to play nearly every day now. I've been down on Hart a lot for his inconsistencies, especially defensively. Realistically, if he's your 1st, 2nd, or 3rd best hitter, you're likely in trouble. Thus far he's been our 4th best hitter (Braun, Lucroy, and Aoki ahead of him), and if Weeks gets it going then we're in good shape. Think of that...if Weeks gets going and Lucroy comes back, Hart is our 5th or 6th best hitter. This lineup is not THAT bad. Also, as much as I don't like Hart in the OF, I love him at first base. It's been a joy having him and Gamel at 1st base this season after watching Fielder the last 6 years over there. I love seeing Hart's right knee dirty every night as it's how 1st basemen are taught to go after low throws. Prince never did that! I used to think Hart was a liability that had to be moved, but I now love him at 1st base. I'd be tempted to let Gamel play OF next year since it should increase our overall defensive abilities.
