... he was worth 5.5 bWAR despite having a 113 wRC+. Canha & Suwinski were each 2.2 bWAR players.
He was the best defensive rightfielder in baseball, & in his 3 previous seasons his wRC+ was 151, 151 & 158, so there is certainly a bounce back possibility, especially considering he'll be 25 next season & how nice these Savant #s look:

& even if a 113 wRC+ is his new normal, he's still a giant bargain. Fangraphs, which only has him as a 4.4 fWAR player says his season this year was worth $35m. So $24.3m per year for 11 years for a guy who still shouldn't be in his prime, isn't that scary.
Now of course there are actual risks, character concerns, PED concerns, broken bones, home/road splits, etc.
But the road thing seems to be an aberration.

Petco Park is the 2nd toughest hitters park in baseball, so I'm not really sure what kind of narrative would cause this to be a thing, especially combined with past road success.
