Wait, what? Nobody would sign Dunn for anywhere near what he got RIGHT NOW based on how he's playing RIGHT NOW. But he wasn't signed RIGHT NOW; he was signed in the offseason, and nothing in the available information leading up to them indicated he would be this bad barring major injury. It indicated the exact opposite, in fact, that he would almost certainly be worth his contract. His performance thus far is a left turn that nobody predicted, but it also doesn't make his contract "good" or "bad" yet since he still has 3.5 seasons left on it and we don't know how he'll perform. He very easily could turn it around and end up producing like he used to, in which case it's a good contract. He could also bottom out inexplicably and it turns out to be a bust. We don't know right now, and those are the gambles that GM's take. We can't definitively say that signing Pena was a better option yet because we're in the middle of a predicted series of events that won't demonstrate if the Cubs 1B decisions were smart ones until next season. Sure, Pena could easily outperform Dunn this year, but so what? Then what if Dunn rebounds and is highly productive for three seasons while the Cubs' plans for Fielder or Pujols go bust? No, I don't want Dunn for 4/56 based on how he's playing RIGHT NOW, but based on him only being 31 and his history going into this season I'm confident that he'll end up being very valuable to the Sox as a player and that I'd wish the Cubs had signed him if the Fielder/Pujols options don't pan out.
