I believe he will save his job.
He acquired Mukhamadullin, Musty, Celebrini, Smith, Dickinson, Askarov, Chernyshov, (and Bystedt, Lund, Havelid, Haltunen are promising on different levels) in a short term. I believe owners have patience and I believe a lot of coaches will want to work with Celebrini and Co.
Everything he needs is continue to find more defensive pieces. He needs one-two more pieces and its not like their rebuild is done - they have draft or two for high picks. Devils had best season year ago and still drafted Silayev this year.
