Interesting waiver pickup to where it looks like Bussi or Patera backing up Korpi. Possibly DiPietro. So if I understand right, because Patera is a waiver claim, he will have to pass waivers again if Boston sends him down? Bussi also not waiver exempt, but not sure about DiPietro. Puckpedia doesn't list him as, but they also have him as a non-roster goalie.
