Keefe isn't soft enough.
That's what the problem is. These divas can't handle a hard noser like Keefe. They need a softer coach.
I wonder if the Stay Puft Marshmallow Man is available.
At best Keefe is mediocre when it comes to being a head coach. He seems to rely heavily on the all star cast of assistants the team has surrounded him with every year. Assistants good enough to have gone on to become head coaches of their own teams.
Keefe himself would make a great assistant.
So long as he doesn't have any actual tactical duties. His head scratching decisions on lineups, deployment, and strategy over the years has led to mediocre results with the outstanding roster he was gifted. Under normal circumstances he would have been fired already.
Keefe's only saving grace is that Shanahan is even softer than he is.
