He had a 68 ERA+ and 76 ERA+ the last two years with a -1.7 bWAR and -0.6 bWAR in those years (though fangraphs has him at 2.5 WAR over that span). So there is a lot more there than just throwing a first pitch strike. That's pretty much the plan for almost every single starting pitcher. The fact is that he is getting paid 17.5 million dollars for the next two years after coming off two extremely horrible seasons. Couple that with him entering his 30s soon and his fastball velocity on a steady decline, I can't see him breaking 5 WAR over the next two seasons.
Though his FIP and xFIP numbers might suggest he is still a decent pitcher, but not a 17+ million dollar a year pitcher.
