I remember sneaky trying to convince me that Travis Wood was really, really good at HR prevention. I'm still skeptical that it is a long-term skill instead of simple variance. That's fine, his HR prevention wasn't this good last year either. But even if you just consider his 2017 an extension of his 2016 performance(in 2017 he's been better in most areas), that's a guy who had 3.0 fWAR in 26 starts(3.7 per 32 starts), and would likely see improvement from AL to NL, better framing catchers in front of him, and better defense behind him. And you'd have him for 5+ years. I wouldn't expect Fulmer to be a guy who starts Game 1 of a playoff series, but that's not all that necessary today either. Plus he doesn't have much financial cost so you can pay Darvish 4/120 or whatever to give you some upside, plus potentially sway Otani this year or next, etc.
