Del Harris leaving Nets

Take a long look at the silver-haired gent sitting next to Kiki Vandeweghe on the Nets’ bench when the game against the Pistons gets underway: You may never see him on an NBA sideline again.

Del Harris, one of the game’s seminal thinkers, has decided to leave the team before the road trip that opens Wednesday in Toronto, according to a friend of the coach.

Harris, who was brought in to be Vandeweghe’s gray eminence on Dec. 4 after the latter moved into the head coaching position, has several reasons for making his exit now – all of them professional issues – but these should not be disclosed by anyone but Harris himself, his friend said.
