I would fire Reirden now. Replace him with just about anyone who has a different perspective on the PP.
I would ride out the rest of the regular season. Barring a miracle, I'd fire Sullivan and do a full search, because the candidates I am interested in are currently employed.
I think this franchise would be doing itself a disservice if it hires its next full-time coach without talking to guys like Marco Sturm, Jeff Halpern, Jay Leach or Joe Sacco.
That's where I am. I think there are really, really promising coaches ready for an NHL gig and if I'm firing Sullivan, I want to talk to those guys, not hire BBQ Bruce or Dean Evason.
