I still don't understand why everyone thinks Roberts is only a "marginal" upgrade over DeRo. It's like everyone just assumes DeRosa is going to repeat last year. Even if he did, that's about the average we can expect from Roberts. Roberts had a WARP of 7.1 last year (DeRo's was 4.5, FWIW). That's a fairly big difference. In 2006, Roberts had an off year at 4.2, which is still right in line with what DeRosa did for us last year. In 2005, Roberts had a WARP of 9.4. So, in the last few years, BRob's least productive year was worth .3 wins less than DeRosa's 2007, which exceeded most of our expectations and left us all pretty happy. I'm not really sure either way whether we can expect DeRosa to produce the way he did last year. On the one hand, he made some adjustments to his swing and since has made clear improvements in his production. Ask some of the resident experts, though, and they'll still tell you that 2007 was flukish and he probably won't be able to repeat that next year. I'm sort of on the fence, but I'm usually optimistic so I tend to lean toward the former. That aside, it's still far from a sure thing. To me, Roberts over DeRosa in itself is more than a marginal upgrade. Couple it with the fact that you either have DeRosa taking the bench ABs away from the likes of Fontenot and others or you're flipping DeRosa for another SP (i.e. Burnett), and it's a clear cut upgrade. I seriously don't understand why people are so willingly brushing Roberts aside like he's nothing special while at the same time overvaluing DeRo. Sure, I wish they'd address SS instead, as it's a more obvious hole, but that doesn't make this acquisition any less palatable.
