Keefe will succeed, because this teams issues weren’t entirely Ruffs fault. The Devils had their 1A/1B defenseman out long periods and a few depth defenseman, they had their 1A/1B offense players out good chunks of the year, Timo played through no knees and a bum shoulder, their best defensive center, having a career year in PTS and F/O being investigated for heinous crimes. To which he was brought charges for, and to top it all off Green as a coach.
I would argue any warm body will do better than last season. Everyone should have a chip on their shoulder to include the coach (who got dismissed for having cap issues and a core who didn’t perform or got injured).
