Re: Top 10 bullpens in MLB history
"MLB history" happened before the 70s, also. I think any attempt to rank "bullpens" and link to MLB history is a flawed principle from the outset. Bullpens evolved and that affects any type of ranking. You can only rank bullpens by era because bullpen usage had distinct characteristics in different periods.
For example, you would have the early years from 1880s through WWII. From WWII-through the 50s, the 60s, the 70s-mid 80s, mid 80s to early 90s, and mid 90s to current. Trying to rank a 70s bullpen with a current bullpen is a category error.
