What veteran coach doesn't appreciate a challenge? There's a lot to work with on this team, first and foremost. I think the raw talent on the roster would be the main draw. Adams doesn't strike me a pig headed and difficult to deal with either. Sure, ownership might have a bad rep, but you also know that any coach who comes here and gets this team into the playoffs will be revered for life (and well compensated) by the Pegulas.
Veteran coaches know that a bottom 5 payroll and a roster that is bottom 5 in experience is way more than a challenge.
And with regards to Adams, the conversations between him and a veteran coaching candidate with options will be about what his plans are to improve the roster this offseason. If Adams tells them that his plan is to add a 4C and promote Kulich or Savoie, that is unlikely to go over well. And that patient, draft, develop, and promote from within has been the Adams approach to this point.
That might not be all that attractive to a coaching candidate.
And who knows what the roster looks like to certain coaches when compared to other options that they might have. This roster had zero players break the 60 point or 30 goal marks this season.
