Overall, but a little inconsistent in recent years. I might be wrong, but I believe I read that ~35 of his career homers wouldn't have been homers anywhere else. At the very least, his home park has propped up his power numbers.
But the most pressing issue for me is that his overall offensive numbers have been in decline. wOBA down each of the last three years, and last year was probably his worst full season. His 4.1 fWAR was propped up by uncharacteristically good defensive numbers.
Defensively, his range isn't great and his arm is poor. As he ages (he'll be 31 at the start of the season) he may have to come off of 3B.
All that said, I'd be happy to give him like 3/90, but I'd have zero interest in him at his rumored asking price. With our miserly ownership, he's just not a player I'd want to see a bunch of payroll tied up in for more and than a few years. I can see him being just a guy in pretty short order.
But I don't think it matters, Jed's not going there regardless.
