A season is on the verge of collapse, a coach is at his wits’ end, and the primary reason for it all mocks the Jazz with every hard screen, every blown rotation and every narrow loss.

Unlike Al Jefferson on the pick-and-roll, there’s no getting around this issue.

"The biggest area of concern is our defensive habits," Jazz general manager Dennis Lindsey said Friday on the team-owned radio station. "That’s been chronicled all year long."

A notably porous defense has gotten even worse in the last two weeks, a period in which the Jazz (33-32) have won just twice in 10 games. The Jazz, who allow 98.9 points per game on the season, have seen that number balloon to 105.5 points in their last eight losses.

The Jazz rank 21st in the defensive rankings, allowing opponents to score 104.1 points for every 100 possessions.

"Ty [Corbin] and everybody else knows that needs to improve," Lindsey said.
