Judging team pitching records these days is a lot like making sense of all-time home run records. It can’t be done. The game itself and in the strength and conditioning have changed so drastically in the last decade that players now looking nothing like their predecessors in the 50s and 60s. Heck, even the players from the 80s had at least a little bit of an everyman look.
The modern pitcher is a finely sculpted athlete, and he’s more specialized than ever before. If he’s a reliever, he has a specific role that typically remains the same all season long.
