When the wheels come off the bus, finger pointing starts. Even those who shouldn't be scrutinized are caught up in the politics of it all, and can't escape. Even when someone in the spotlight takes some blame for what's happening, it's done with the intent that they're confident they'll be given absolution by the loyal fans, because they're being so "open" with them as to what their role is, in what happened.
Where we're at today didn't happen over night. It started when McCarthy began turning a deaf ear to assistant coaches and players, deciding he'd be the sole decision maker on the sidelines. Eventually that destroys the continuity, and the way the team actually plays on the field, even though you can't physically see any specifics that indicate this is happening.
I was an assistant coach on a team that went from winning our first 5 games against top competition to losing our last 5, against bottom feeders, simply because the head coach decided that what we'd been using to win those 5 wasn't what he wanted to see from the team. He wanted things done a specific way, and we were not allowed to vary one iota from his agenda. He stated so in front of all the coaches and players.
The next practice, things started to deteriorate, and by the time we reached game day, no matter how hard we tried to keep things on a level keel, we were blown out on both sides of the ball by a team that had not won a game all year. In fact, it was the only game they won all season.
At the end of the year, all the decent assistant coaches quit, and those who were nothing but butt kissers stuck around. The following year, I had my own team, and we trounced them by over 40 points, even though we let up on the gas the entire second half.
Believe what you will on these issues, but those who have coached know that so much of the game is dictated by your intensity of play, and trust in the coaches and players next to you, to do their job efficiently.
