The good news: fixing a broken bench is a plausibly accomplishable task for an NBA general manager in the middle of the season.
Last year’s Houston Rockets are a good example. Their bench started out abysmally, just like the Jazz’s. They found that veterans they assumed would contribute in big roles, like Carmelo Anthony and Brandon Knight, weren’t good enough anymore. They found that role players who had contributed in big ways in previous seasons, like James Ennis and Michael Carter-Williams, wouldn’t be able to help as much as they thought. And so all of a sudden, they needed help fast.
