Taj Gibson is starting his 16th NBA campaign, this time with the Hornets after being waived last season by the Knicks. He still hasn’t given up the goal of coaching, however. “It’s there,” Gibson told The Post. “But one thing before I do, I want to be extremely good at my craft. That’s why I was taking most of the coaching clinics in the summer. Just working and getting a feel for guys and getting a feel for different things in the coaching field. Even if it’s not coaching, if it’s management. Just learning all facets of the trade.”
