While this will no doubt be twisted into a pointless, I'm-bored-and-its-offseason Ruff rant I do think this could be an interesting discussion about Dineen as an NHL coach.
My thoughts on Dineen: While inexperienced I think he could be an excellent head coach. Panthers were good to get him.
My thoughts on Ruff: Proven, good coach with a system that works. His been a good coach working with poor teams but doesn't seem to be the best motivator when the team is down, however this can be attributed to the mental toughness of the team.
I think Ruff deserved one more year at the time given the circumstances. If it was this offseason and Dineen had expressed an interest I would say yes, fire Ruff and hire Dineen. Last offseason, no. However given the fact his not available I don't know of a better coach at the moment so keep Ruff.
