Soup came to me with that offer. I'm assuming since he leads the league in saves, he decided he could sacrifice some in order to acquire a guy who could potentially get a good amount of SP-eligible holds.
I actually didn't really need Dyson, since Clippard just inherited a closer job, but I liked the value. I now have 5 closers, which is definitely overkill, so I'm open to moving one of Osuna, Dyson, or Clippard for a SP (ordered from most to least expensive).
