After what happened the first time he retired I am certain Snyder is going to pick his successor this time around and make sure the program is on solid when he leaves.
My best guess is what others have said, he is already on the staff. Either Koenning or Dimel. As for BV, from what I know which isn't much, Snyder still likes him and it was Wefald that had something against BV FWIW.
