If Keefe leaves or gets fired. We need to find a better coach of course. Yeah a lateral move wouldn't be a disaster: it would simply be an exercise in futility.
Keefes Xs and Os are fine. It's on the top players to work through playoff issues. That's entirely on them and not on any coach. He is not above criticism, but as long as he draws the line and controls ice time properly, the team knows what is expected of them.
In any sport I've been a part of I have never thought "we are losing because of our coach".
The key for Keefe will be in player selection come playoffs. He has to see the value in a player. Guys like Reaves who will "rah rah" the team. The type who probably dishes it out on teammates but can take some ribbing too. He will ALWAYS have teammates back though. That is his DNA.
We all know those types. Important in competitive sports and it sometimes takes a period of time to adjust to their personalities. As long as he is responsible defensively and knows when to do what, he is an asset. He contributes to the wins in his own manner.
Benoit is another type. Like the Boosh when he was here the first time, you can see he constantly wants to learn and improve. These are the guys in the trenches. They don't need anything but the knowledge that they did everything they could to win for the team. Not as vocal as a Muzzin but just as determined.
You cannot have enough of these players. Their types quietly win Cups.
You go down the line for the player choices Keefe has to make and it will most decide the teams outcome. At least that which is in their control. Even guys who don't play have a serious role. It is in being positive. Kessel won a ring and didn't sulk a minute as he sat out the entire playoff run.
