There's likely to be a difference between his demands and what he gets, but reports are Dunn wants 4 years. I'd guess Gonzalez will re-up for 6-7 years tops. That's not all that significant. Especially if Gonzo goes 4-5 years with the idea of getting one more big contract after this one. I don't want to talk down our prospects first off. I'd hate to give up any of those players, but there are significant questions about each of them, save for Wells. However, Gonzalez has 6-7 WAR upside. Dunn hasn't been more than a 3.4 WAR player since 2004. Granted, Dunn and Wells together equal the same number of wins as Gonzalez's upside, but Dunn is likely to regress and perhaps quickly from here. Gonzalez is likely to get better. While Wells will likely also get better, we have an abundance of high quality pitchers ready for the majors and could take the hit of losing a couple of them in this trade. I don't think Dunn turning 31-34 during his contract while Gonzo will be less than 30 for the first two years of the deal can be understated. Gonzo is also, I'd say, more likely to age well than Dunn (better walk and K rates for Gonzalez). Dunn is asking for $15 mil a year and might get close to that with first base now being a proven position for him – he certainly will if he relents and becomes willing to go to an AL team to DH. The absolute max I could see Gonzalez getting is $25 mil a year and probably less in this economy. There's now way I can see us getting a Cliff Lee for no more than $10 mil a year. I can understand not wanting to give up a lot of talent for one player, but with our farm system having nobody on the horizon at first base, we pretty much have to make a move for one. As much as I like Adam Dunn, I just don't see him being productive enough into his mid-30s to warrant the kind of money he's asking for and may very well get.
