Look, we can make the argument that signing Marcum precludes us from signing a better pitcher like Josh Johnson. We could use that money in any number of better ways--just because there is money coming off the books, doesn't mean we should become free spending and invest in players the team doesn't believe in. Firstly, this misses the context of what already has happened this off season. Secondly, Marcum was not a 3 or 4 WAR player last year. Marcum, at this point, isn't replacing a negative WAR player like PJ Walters, he'd be replacing whoever is in the number 5 slot Harden/Hendricks/Gibson. It becomes diminishing returns when you spend millions of dollars to upgrade a position by a minimal amount of WAR (or wins). Two things: 1) The difference between the two last year in WAR was .5, the difference in xFIP .1. 2) The Twins might actually have legitimate concerns about Marcum's heath. (I agree Marcum gives us far more to hope on, but that doesn't mean he'll produce like he did a couple years ago with the BJs). And really, you're better than predicting the rosiest outcome for your pet free agent of choice (3 or 4 WAR) and the worst outcome for the players he's replacing (-1 WAR). Come on, man. As I've said before, I'd like Marcum on the team, but there is a point of diminishing returns by upgrading from mediocre to average, as each run on the ladder becomes excessively more expensive. I'm for such overpayments when we're actually in a postion to compete and we have a better sense of our actual needs for such a team .
