You new mate?
Pick literally any example of a coaching change since 2005 and you'll have 60-70% of them showing immediate positive impact. Pens are quite literally the poster boy for such a thing.
Also where the f*** did you think Edmonton found their coach? Some magic hat? There's coaches around. Do some research. I've name dropped a bunch.
Todd Nelson
Jay Woodcroft
Jay Leach - He's been someone teams are starting to get very curious about as a HC option in interviews.
Karl Taylor
John Gruden
Other names - not ones I'd want but names nonetheless
Todd McLellan
Lane Lambert
Dave Hakstol
D.J Smith
I'd hire none of these blokes btw. None.
I just hope they don't sign a loser like Joel Quenneville.
The assistant I'd want would be David Carle, that's a future coach right there as well after some experience as an NHL Assistant Coach if he came over to be AC to one of Nelson or Woodcroft. Personally, a huge fan of Todd Nelson. Love his style. Open to criticism and feedback and won't punish players for it, his players will skate through a wall for him. He has paid his dudes, he's the most deserving of the bunch imo.
