Exactly. John Hiller was the 1st guy I thought of. Not only survived a heart issue. But guys like him and Marshall pitched multiple innings nearly every appearance. And on top of that they could start if asked. And when they started,they could and did pitch CG. Several of those names pitched more innings out of the pen than today's starters do. The HOF should be difficult to enter. There's a lot of Joe Nathan types. Really good players. Not quite HOFers
