Idk. It just feels like he's going through the motions relative to a few years ago. He obviously hates the landscape (who can blame him for that?). Him not shaking up the staff after the last two seasons to me is him saying "I'll do what I want, fire me if you don't like it. I don't care either way".
If you want an example of actually not working hard enough, it's Tariq Francis. Complete joke of a signing. He's at a mid-major at best if it wasn't for the BK connection.
At best it's what you said, he's trying but is too stubborn to make changes in his staff, his approach, etc.
