4.1 fWAR last year, 22.7 combined the last 5 seasons. Obviously a bit of a down year this year with regards to results but his FIP and xFIP are right in the same range as previous years and he's at 2.6 fWAR (I know pitching WAR is meh, just easy to quickly review) so there's probably some bad luck involved. I think this is a great move.
