How do these guys justify leaving Billy Wagner off while not using their maximum amount of votes? You might as well just not let relievers in if the current threshold is that nobody with a lesser resume than Rivera or Hoffman deserves to be in.
The only current potential HoF relievers that have been around long enough that it makes sense to compare them to Wagner are Jansen, Kimbrel, and Chapman. And all of them will need a few more good seasons to be on Wagner's level.
