Interesting perspective and a nice comparison in terms of the value the Twins may have been getting as compared to other teams and what we may have to consider with regard to the Twins in the future. A couple of thoughts, though: -It would even better to see numbers here, and especially important to see what other clubs were getting for the money with similar pitchers. -In terms of WAR, remember that zero is a replacement player and not "average." There's actually also a vast difference in the value of 1 point of WAR (and thus 2 and 4 are very different). A WAR 2 is really the minimum WAR you want/expect from a regular player in the MLB (everyday position player or regular part of the rotation). A 4 is considered a good player. As an example, I think we'd all agree that Pavano had one of his worse years as a Twin, and with an ERA of 4.3 but he still posted a WAR of 2.0. -Finally, I think that Thrylos lays out some additional things needed when you have pitch to contact pitchers, but I'd add that pitch-to-contact pitchers can do well over the course of the regular season (especially in the AL Central), but when it comes to playing against heavy hitting playoff teams, you need pitchers who can miss bats.
