I don't necessarily assume that the two are mutually exclusive. One of the things that bothers me about piling on Pau is that he's clearly not being used to advantage. The argument is that D'Antoni will never do that because of his system, but I don't buy that argument -- or at least I'd like to think that "offensive geniuses" are smarter than some idealized philosophy of basketball.
If D'Antoni really is a great coach -- and if he senses the opportunity he has -- then he'll do what all great coaches do: modify the offense and defense to feature the skills of the players on the team. Maybe LA doesn't have ideal players for run-and-gun, but it's still got good players, and a really great coach would make the most of them.
So in the end I see the next few months as a real referendum on D'Antoni. Can he figure out how to make the most of what he has? We obviously won't know that until everyone's healthy. If things look ugly at the end of February I wouldn't have any problem with focusing on D12's future.
