Thee wasn't anything new about his swing. Whatever was new didn't show up in games.

His adjustment was along the same lines Rizzo went through in loading his hands lower. The issue I see is his swing is level vs in a upward plane. Which means line drive and ground ball to 2B if he gets on top of it.

It really comes down to BABIP with him.
2011 .260 ended up with BA .227
2012 .319 => .269
2013: .281=> .254
2014: .308 => .271
2015: .329 => .293
2016: .266=> .230
2017=> .284=> .259
so 2017 and 2013 were pretty close years. 2011 and 2016 The years that he pushed over .300 BABIP his BA got up into the .270 range. 2015 was a blip as far as his trends go and might be just solid luck or hitting to the park.
But what I took out of it was his BABIP did improve and his BA increased by .029 which is in alignment with past years.
ISO .130 better than 2016's .094 but below his career avg of .150.
over all he is not going to become something he is not. He had a career worst for the 2nd time then matched production of another year.
2017
BABIP: .284 Career avg: .300
ISO: .130 AVG: .150
SO%: 13.9 AVG: 17.6 Career best
BB 8.5 AVG: 10.4 worst year.
I take it as he can afford to add loft to his swing with that low of a SO rate and his ISO suffering. Or you lead off with him and make him a spray hitter. He puts the ball into play and needs to work on going to left and left center more.
Regardless this is something to mill on.
