ESPN has let go of NBA Countdown’s Jalen Rose, The Post has learned. Rose, 50, had been on ABC/ESPN’s top NBA broadcast for a decade, which was especially impressive because of the amount of changes the network has made over that time. The Post first reported Friday morning that ESPN was laying off around 20 on-air personalities. Top NBA analyst Jeff Van Gundy was also let go by the network. ESPN had reduced Rose’s role at the network after his daily program with David Jacoby was canceled at the end of 2022.
