The thing about Hurley is, he has a plan, and he tells you what the plan is. He's stated numerous times that in the early phase of his rebuilds he acts like a maniac for the purpose of instilling a will and a fire into groups of players that had none.
He's also stated that the Dan Hurley on the sidelines in years 3, 4 and 5 is a lot different from the Dan Hurley in year 1. While I'm sure year 5 Dan Hurley is still a quasi-maniac, I have to believe that some of the antics this year are very intentional. It's like he's trying to drag the team to a new level of toughness, passion and intensity by being completely over the top himself. When you're trying to teach a team not to play soft and scared on the road, there is some logic behind ostentatiously acting like you'd fight everyone in the arena if you had to. A junkyard dog doesn't turn it on and off.
People can debate the merits of the strategy, but I think it's clear what he's doing.
I also think it's working to some degree. One of the unremarked moments from yesterday's game was the passion Carlton showed when he picked up his 4th foul. Never seen anything remotely close to that emotion from him. He had a tough whistle and I'm sure he was frustrated with the refs, but mostly I think he was frustrated with himself and that he wasn't having the kind of game he thought he should. He expected more from himself. That's because of Hurley. That's what he's building.
