... or contract, as hitters constantly adjust to the pitchers' "book" that circulates around the league quickly.
The worrisome part of Story's slow start is that he isn't just swinging and missing at one pitch in one spot -- like JD and his kryptonite low-and-away slider. Story is whiffing on virtually every breaking pitch: outside, inside, down in the zone. I don't have data, but it seems like a weakness in every game.
It's interesting to compare other star hitters that left Colorado recently. Arenado batted .293 with an .890 OPS in 8 years as a Rockie, and is .268, .841 as a Cardinal. DJ LeMahieu hit .299, .760 in 7 years for the Rox, then improved in 4 years in NY: .308, .833, and hit more homers (to the short porch in Yankee Stadium). Going further back, Matt Holliday hit .319, .936 in 6 seasons for Colorado, but was still good after: .287, .859 in 8 more years. Larry Walker was a star in Montreal, but a Hall of Famer in Coors with ridiculous numbers.
Story averaged .271, .857 in 6 years as a Rockie. The difference Red Sox fans need to be aware of is that DJ, Holliday and Walker were all batting champions in Colorado. Story was an NL strikeout champion, and has averaged 188 Ks per 162 games in his career...
Other Red Sox career Ks per 162: Verdugo 92, Kike 105, Vaz 108, Bogey 127, Devers 149, JBJ 154, JD 163, Dalbec 200.
