This is numbers given as evidence to support an opinion that’s different than the argument. Here, I’ll ask
- Why is Davis likely to exceed his WAR value going forward if he was “fantastic” in 2017?
- can you speak to Why Davis Lost velocity and command?
- can you speak to Why he was more prone to HR than ever before?
- Why is Davis going to outperform the poor history of relievers his age?
- Why would you pay Davis to be a top five paid reliever if he was just the 48th most valuable?
- What’s the history of relievers ages 34/35?
- Why would I expect Morrow and McGee to revert back to zero or worse pitchers when those years were rehab related?
#1 - pitching more innings. He only threw 58.2 innings for the cubs last year largely because he wasn't needed that often in the first half. As a comparison he threw 67.1 innings in 2015 and 72 in 2014. Jansen threw 68.1. Kimbrel threw 69.0 innings. That's 15% more give or take. WAR's a counting stat and therefore the more you throw the more "value" you have. And he was fantastic in any sense of the word. he had a 2.30 ERA and blew 1 save all year.
#2 Lost velocity how? Fangraphs had him at 94.6. While he was at 95.5 in 2016, losing ~1 mph isn't uncommon year to year. if he were down 2-3 mph then sure you worry a bit. But frankly the loss of velocity isn't really important because velocity is means to an end(K's). How was his k rate in 2017? 12.12 was the second best rate of his career behind the 13.63 he put up coincidentally in his most valuable year of 2014.
With regard to the command that's a more legitimate concern to me. The simple answer is I don't know. I'd love to be able to tell you exactly what went wrong there but I really don't know. However what I can tell you is whatever was wrong happened in July and August. In the first half of 2017 his walk rate was 3.60 which is a little higher than his career 3.36 rate but not crazy. In july his walk rate was 7.88 and in August it was 6.52. It dropped back down to 2.77 in September but those two months made his second half walk rate 5.02 which effectively accounts for the when. Maybe he had a nagging injury that wasn't enough to send him to the DL. Maybe he just lost his release point. I'd have to dive way deeper than I feel like doing to give you a firm reason but I do recall July being a time when the cubs starters were shit and the bullpen got way over used. As an another example here Edwards walk rate in July was 7.94 and August it was 5.56. So my guess that they were over used seems plausible. But like I said, if you have a better answer I'm open to opinions.
#3 See every cubs pitcher? HR's were up across the majors not just Davis. You're talking about a 4% increase which isn't nothing but Jon Lester was up 5.6% over his career rate, Hendricks was up 4.1%, Arrieta was up 3.1%, Quintana was up 3.8%, and Lackey was up 7.8%. It wasn't just Davis that had that issue.
#4 What poor history for people his age? Even if he does decline from age 32-35 which I think you're vastly overstating it. He's not going to suddenly be washed up. You look at Trevor Hoffman 32-34 and 36(was hurt at 35) he put up 5.7 wins. Joe Nathan 31-33(was hurt age 34) put up 8.7 wins. Rivera was 9.3 wins 32-35. Billy Wagner 32-35 put up 7.1 wins. If you want to do this even more broadly there were 699 player seasons from 1990-2017 where someone 32-35 threw qualified innings. Best season was 2007 Rafael Betancourt at 3.3 wins If we can agree that 1.5 is a decent enough season there were 94 of 699 where relievers put up 1.5 wins or more(13%). If you say that 1 win is acceptable but not desirable there were 181 1 win seasons(25%). If we further narrow that to guys over 9 k/9 there were 150 player seasons over that same time period. 55 of that 150 were 1.5 wins or better(37%) and 85 were 1 win or better(57%). If we further narrow that to guys over 9 k/9 but also under 4 bb/9 there were 111 player seasons 53(48%) of which were 1.5 wins or higher, 75(68%) of which were 1 win or more. In other words, if you can concede that Wade Davis age 32-35 will have a 9 k/9 or higher and below a 4 bb/9(rates as a reliever are 11.67/3.24) I'm telling you're there's a roughly 50% chance he'll put up 1.5 wins or higher and a 2/3 chance he'll be at least 1 win. I'd hardly suggest those numbers indicate poor performance for players age 32-35.
#5 By your own argument forecasting relievers year to year is difficult. So why are you using an individual year to assess judgement? Since Davis is likely to get a 4 year deal would it not make more sense to compare Davis to relievers the past 4 years? At 7.4 fWAR the past 4 years he's #6 in baseball behind Jansen, Betances, Miller, Chapman and Kimbrel. And even if you were to cut 20% off his performance those 4 years because he's "getting old" at 6 wins he'd still be the #11 reliever in baseball behind those names plus Giles, Cody Allen, Robertson, Britton and Osuna
#6 see #4 because it's literally the same question But if I narrow it just to 34 and 35 to humor your argument with the same caveats(9+ k/9 < 4 bb/9 years 1990-2017 over qualified innings) there are 42 seasons. Of those 42 seasons 17(41%) had 1.5 or higher fWAR and 23(55%) had 1 or higher fWAR. So sure, you're marginally worse 34-35 than you are 32-35 but is -7%/-13% that surprising? Losing half a win every 2 years after 30 its a pretty normal rule of thumb to go by.
#7 You realize Morrow has a significant injury history right and that the entire reason he became a reliever was he couldn't stay healthy? So to answer the question why would he revert back to 0, simple he gets hurt. He threw 16 innings in the majors in 2016, 33 innings in 2015, 33.1 innings in 2014. A typical reliever you want to hit at least 60. He hasn't hit 60 innings in the majors since he was a starter in 2012. As for McGee, he's the prototypical reliever you're talking about who isn't consistent year to year. He was worth -0.2 wins in 2011 over 28 innings, 2 wins in 2012 over 55.1 innings, 0.6 wins over 62.2 innings in 2013, 2.6 wins over 71.1 innings in 2014, 1.1 over 37.1 innings in 2015, -0.3 over 45.2 innings in 2016 and 1.5 over 57.1 innings last year. He's literally only had 1 time(2014-15) where he had back to back years over 1 win in 8 years in the majors. So, judging solely on his history he's just as likely to be bad next year as he is good.
We can play this game all day. There aren't going to be pristine relievers who have 0 questions because if that player exists he's either A) Mariano Rivera and locked up to the same team for so long you never see him in FA or B) he's a starter. But I'll humor you. Britton saw his k/9 drop from 10.83 in 2015 and 9.94 in 2016 to 6.99 last year while his bb/9 went from 1.92/2.42 to 4.34 last year. That's a far more concerning jump than Davis. Already talked about reasons to doubt McGee/Morrow so I'll skip them. Greg Holland? Saw his walk rate rise to 5.24 in 2015 then missed all of 2016 and it was 4.08 in 2017. His HR/FB rate went from a career average of 7.2% to 11.3%. He's also essentially the same age as Davis since you perceive that as an issue. Addison Reed? Saw his HR/FB rate go from 8.9% on his career to 12.5%. He's also a guy that is at 9 k/9 which is troubling for a reliever as mentioned with Ziegler/Melancon. Joe Smith? The cubs had him last year and how that work out? He's also going to be 34. Anthony Swarzak? Actually don't have that much negative to say about his 2017 but that was clearly a career year for him. He has no other year over 0.8 wins. Mike Minor? I don't hate him either but he's had trouble staying healthy. Missed all of 2015 and most of 2016. Bryan Shaw? He's ok but a career 8.03 k/9 is worrying and he's never been a closer really. Just a decent set up guy. Is there anyone else worth mentioning? Think everyone else at best is a set up guy.
Regardless, any team that is considering signing someone like davis who's over 30 is going to phase in regression as part of their offer. And I literally gave you that as an example. Him going from 7.4 wins the previous 4 years to 6 wins the next 4 is a 20% decline. That's a fairly massive decline in performance and even then he's still a top 15 reliever. In order for him to be outside the top 30 relieves he'd have to suffer a 52% decline in performance. And if you want to go deeper, Davis' soft contact was the highest of his career at 28% last year and his swinging strike rate was 15.5% which was also the highest of his career. In other words, hitters weren't handling anything he was throwing. The soft contact rate was 8th best among relievers with only Betances, Jansen, Peter Moylan, Matt Albers, Dan Jennings, Bryan Shaw and Ryan Madson better. The swinging strike rate was 22nd in the majors among relievers. That list has more surprising names than you'd expect but to put 15.5% in perspective, Andrew Miller was 16.3%. Giles was 16.4%. Jansen and Kimbrel were at the top at 18.2% and 19.8% respectively. Chapman was at 13.6%
Literally the only valid concern I see that you can levee against him from 2017 was the walk rate because batters were swinging thru more of his pitches than ever before and when they made contact he had the highest soft contact rate of his career. That's literally everything you want from a high pressure reliever minus the walks.
