It's not completely what they think. It's that they've been ran into the ground by Dunnlap's practices. It was a real worry before the season. Dunlap's manage to run biz into the ground and considering how in shape he is. It's saying something and its not good.
That sir is false. I watch their practices. They don't practice any harder than what they did under any previous coach or harder than what any other coach in the NBA would do. He may has worked them to death mentally. NOT physically. He isn't retarded.
