After Cavaliers coach Tyronn Lue stepped away from coaching to focus on his health Monday, the Nets’ Joe Harris — who played under Lue in Cleveland — expressed empathy for his former coach and the pressures of his job.

“That might be as difficult a head-coaching job as there is in the NBA,” Harris told The Post before the Nets beat the Grizzlies, 118-115, at Barclays Center. “Even the constant media demand that you have in Cleveland is different to anywhere else in the NBA. The amount of people he has to talk to about everything every day, and it’s your first head-coaching job.

“I can’t imagine all the stress that you would have when you’re underneath the microscope about everything, I’m sure.”

Harris played in Cleveland from 2014-16, the first season with Lue as associate head coach and the second during Lue’s midseason debut as the headman.

“Your health is the most important thing at the end of the day, so you don’t want to compromise that just because you might be in the middle of the season,” Harris said. “Anybody else has complications health-wise they’re able to take time off from work, so he should be able to do the same.”

The 40-year-old Lue spoke of chest pains, loss of sleep and “other troubling symptoms” in a statement, while ESPN reported that he had coughed up blood.
