Wow, some terrible "analysis" there. Anderson has a 7.3 K/9 in his 267 IP (he was better in the minors), a 4.17 FIP and 3.96 xFIP, and a 1.2 HR/9. That makes him just a touch worse than league average (2015: 7.8 K/9, 1.0 HR/9, 3.96 FIP, 3.96 xFIP). Meanwhile, Miller Park is not really any more or less hitter friendly than Chase Field (both skew more hitter-friendly than average), and Anderson is not an extreme flyball pitcher. By any metric, in 2015 Anderson was substantially better than Matt Garza and Wily Peralta, and more or less equivalent to Nelson and Jungmann. If you rank our projected rotation by xFIP from 2014-2015: Anderson, 3.96 xFIP (267.0 IP) Davies, 3.96 xFIP (34.0 IP) Peralta, 3.97 xFIP (307.3 IP) Nelson, 4.02 xFIP (246.6 IP) Jungmann, 4.10 xFIP (119.3 IP) Garza, 4.18 xFIP (312.0 IP) Obviously nobody is expecting him to be the best pitcher on the team though. I'd say five years of a slightly-worse-than-league-average SP who can either absorb innings at the back of the rotation, or have a nice first half and get flipped for prospects, is a great return. Not sure what that author is talking about at all.
