North Carolina announced an eight-year contract extension for head basketball coach Roy Williams a week ago. The deal is likely intended to cover the remainder of the Naismith Hall of Fame coach's career in Chapel Hill.

The extension, which marks the fourth time Williams’s contract has been amended since his return to UNC in 2003, is worth $21.5 million in salary and supplemental compensation. The deal runs through June 30, 2028.

“I’m grateful and humbled in the University’s continued faith in my leadership of the basketball program,” Williams said in a school release. “When I coached at Kansas my contracts with Nike and our media partner were private, and UNC respected and honored that for 15 years. However, times have changed and understanding the environment that college basketball faces now, Chancellor Folt, Bubba (Cunningham) and I agreed the correct and proper thing would be to disclose those terms.”

Before UNC faced Kentucky last Saturday, Williams commented more on his new contract extension and his intention to coach well into his 70s. He spoke on what he enjoys most about coaching and the special moments that keep that desire to win burning. Williams is 68 years old.

"Recently I have been saying, as long as I feel good and I have my health," Williams said about still coaching. "I enjoy what I am doing. I really do. It's fun. You face some adversity. You face some tough times. But that is part of life too."

Williams was hired by North Carolina in 2003. He has won three national championships and been to five Final Fours in his 15 years as head coach at UNC. He is 850-230 overall in his 30 years as a head coach, including 432-129 at Carolina. The Marion, N.C. native is 77-25 all-time in the NCAA Tournament, including a 43-11 record at UNC.

While Williams loves the wins and the championships, it comes back to his players. North Carolina players keep coming back to Chapel Hill after they graduate and leave Chapel Hill and much of that is because of their relationship with Williams and the family environment he has helped to continue at Carolina.

"The three national championships jump out at you. But just the relationships I have with the players, that will last a lifetime, too," Williams said about the best parts of his time at UNC.

"My association with my players is still the most fun to me," Williams added. "Coming into the locker room after the big wins and acting a fool, I enjoy. I enjoy my time with them on the court in practice. I enjoy my time with them when we travel."

Williams's eight-year contract provides even more stability for UNC basketball, which has only had four head coaches since Dean Smith was hired in 1961.

"For me, I was very flattered, the comments that were made... very flattering," Williams said about the contract extension and the ensuing reaction. "Pretty neat deal. I am happy about it. As long as I've got my health, I'm okay."
