Indeed, the last three largest FA deals have seen major injuries and or underperformance, when healthy.
$140M/6 Story- 145 games out of 486 and just a .681 OPS
$90M/5 Yoshida (plus a $15.4M posting fee)- 173 games out of about 239 at .754
$38M/2 Giolito- No GS in year one.
We did do well with some mid-level deals like Jansen ($32M/2,) Martin ($17.5M/2,) and Turner (~$15M/1) but a few not so good- like all the $10M/1 deals: Kike II, Kluber & Richards. (The $18.8M/2 extension to Barnes was a bust.)
Bloom did much better with the $3-7M deals, like Wacha, Hill, Duvall, Strahm, Renfroe and Kike I at $14M/2 and Paxton at $10M/2.
