I'll add Dave Johnson from 1989-90 to the mix. Even if Johnson was slightly below average going by ERA+, he was miles better in that 1.5 year stretch, than the rest of his career when he was absolutely hammered. Plus, I always admired how he gutted out an emergency start against the Blue Jays the final weekend of 1989 season after Pete Harnisch got scratched because he stepped on a nail.
It really does get to the point where some know they've come full circle.
You know, for quite a while now, every time I passed a cemetery,
I felt as if I were apartment hunting.---Prof Wutheridge from The Bishop's Wife (1946)
