The organization fully expected to be a playoff team going into this season. They've been in win-now mode for years. They fired Monty Williams a year and a half ago despite a playoff appearance that season.
They're not going to suddenly reverse course less than a month into the season. With Holiday just returning, they'll give this team time to play its way into the playoff race, assuming Anthony Davis stays healthy.
You can make a very strong argument that New Orleans should be in rebuilding mode right now--and I would agree--but that's not going to happen unless ownership calls for it. Neither Dell Demps nor Alvin Gentry have the job security to eschew a win-now mentality in favor of a long-term approach. Those guys are too busy fighting for their jobs right now to worry about what's best for the franchise a few years down the road.
