I'd like to hear your arguments. This is what I said in another thread: My argument for the Diamondbacks is that just about their entire lineup consists of highly regarded prospects playing their in their first and second MLB seasons last year. Considering that they managed to have the best record in the NL last year despite their prospects learning on the job, I would expect vast improvement from their lineup. If they produce like last year, you are right. But they obviously got a lot better in SP, essentially replacing Livan Hernandez with Haren and Petit with Randy Johnson. FYI, the Diamondbacks team OPS by month: April: .714 May: .757 June: .700 July: .706 August: .715 September: .811 Playoffs vs. Cubs: .890 The problem with the D'Backs is offensively, they don't have one sure thing. Their whole team is like 23 years old. They could be very good if they all take big steps, but they could be terrible if none of them do (offensively at least). More than likely, they will be below average with an great starting rotation. Randy Johnson will probably be hurt at some point though. I can see them being in a lot of close games this year, so if they get lucky/manage their bullpen perfectly or whatever made them outperform their pythag last year they can be a contender, but it seems unlikely. At least to me.
