Here's Harvey's write-up from Baseball Prospectus' 2016 Annual, published just before the start of the 2016 season: On October 23rd [2015], David Wright, Jacob deGrom, Wilmer Flores and Harvey were guests on Jimmy Kimmel Live in front of a live crowd in Brooklyn. The former three could not stop grinning. The captain Wright did the bulk of the interview. Flores spoke of what it's like to cry in front of millions of people, and deGrom's hair became a popular Halloween costume. Harvey trailed off after 10 words, all about Chase Utley. When the segment was over, Kimmel issued Harvey a quick apology, saying he'd run out of time. Harvey didn't seem offended, just uncomfortable, like he didn't want to be there. That's where he always fit with the 2015 Mets, for what ever reason, while everyone else was grinning, there was Harvey with a scowl, always with his own business to attend to. Nonsense story lines about innings limits and model girlfriends and missed workouts didn't make him look like a star, on this team, they made him look like an outcast. On the mound, he wasn't quite the same. The line drive rates on his fastball and changeup soared in 2015, and he got lost in the crowd of so many other incredible young talents. Yet he adjusted and became a more complete pitcher with massively improved breaking stuff, and in the postseason we found out he has real guts. He is, in all likelihood, a good guy and a fine teammate. But now that the narrative ball is rolling, it will be tough to stop. And here's his write-up from this year's BP: Well, The Dark Kniight Rises was a pretty lousy movie by the end. Gotham's former savior was brutal for half the season, and all involved claimed he was healthy, which was alarming because a healthy Matt Harvey should never be that bad. It was almost a relief to find out there was an underlying medical diagnosis -- except the diagnosis turned out to be thoracic outlet syndrome, a nerve and blood vessel issue in the chest and shoulder that has been the bane of many good pitchers' existence. Research by Craig Edwards of FanGraphs and Carl Triano of Beyond the Box Score shows that the range of outcomes for pitchers suffering from thoracic outlet syndrome varies wildly. Some pitchers, like Kenny Rogers and Aaron Cook, have returned healthy and nearly as effective as before, while others never pitched well again, like Chris Carpenter. Overall, the group was a bit worse than their career marks on ERA- and FIP- upon returning, and many had their careers ultimately shortened. But no pitcher has ever had thoracic outlet syndrome as an ace in his twenties, like harvey. We'll start finding out in spring training whether Harvey can start to being Christian Bale in 2017, as the Mets certainly need him to be more than Ben Affleck.
