Melvin said that "some of the names (reported) are right and some aren't right" - if you take that to assume one of the guys mentioned wasn't actually interviewed, my guess was that it was either Wedge and/or Wallach. Both of those were reported by Ken Rosenthal, who isn't exactly a bastion of reliable rumormongering. Roenicke is a possibility to add to that group, too. OTOH, it was reported alluded to elsewhere (I think an LA Times piece linked earlier in the thread) that Wallach was interviewed. So, given that Bob Melvin, Cora and Listach were almost certainly interviewed and Wallach was probably interviewed, that leaves up to four guys who we may not know about.
