Let's set aside the issue of WAR (bWAR vs fWAR), for the time being, he hasn't had a season like that in 10 years. Expecting a 35 year old to repeat those results is not a bet most would be willing to make. I'm not sure what people are thinking here. I suppose in the universe where the Cubs need warm bodies to make starts, he's a guy. Just looking at fWAR because I think its better for pitching (correct me if I'm wrong), but Miley has averaged 1.9 fWAR over his last 10 seasons. It's not the 2.9 WAR he had last year and you are right to be a little concerned about age regression but I'm not sure you are doing better in FA if you are looking at a relatively affordable starter with no long-term obligation. But you are saying to set aside WAR. I don't see anything in his numbers that jumps out as an extreme outlier last year. K/9 is actually lower than career average. His walk rate is lower than recent years but not a career low and not out of line with a majority of his career. BABIP is higher than it was in 2 of the previous 3 years, xERA, xFIP also are in line with several other years in his career. I think it was TT that said that if this was $10m of a $40m budget then yes its not a great move, but if its $10m of a $90m budget then I think its a smart move considering the number of holes the Cubs have to fill. My sabermetric knowledge is a bit dusty at this point (who has time for fun things anymore?), but defense-independent pitching statistics [as a bucket, not the old offshoots of DIPS in particular] were usually more predicative in value, with less variance year-to-year. So fWAR, thanks to its reliance on FIP, has long been my go-to when I'm trying to evaluate what a player's talent level really is. There is a vanishingly small number of pitchers who have shown abilities to outperform their components over large sample sizes. Matt Cain is a classic example. Kyle Hendricks is sometimes thought of as one. Prime Jake Arrieta was one as well. Last I checked in, there was still a lot of work going on in figuring out how those guys beat their peripherals so well, but it was thought to have a great deal with the ability to induce weak contact. But that seems to be a skill that may degrade, possibly quite quickly. One season Matt Cain just lost it. Same for Jake. Neither really got it back. But I digress. The long and short of it is that there are startlingly few such pitchers, and figuring out whether a particular pitcher currently outperforming their peripherals is doing so as a talent or by luck is a crapshoot. And it doesn't appear Wade Miley is such a pitcher at any rate. So yes, I believe you were correct in using fWAR.
