North Carolina awarded coach Roy Williams a four-year contract extension Thursday that will keep him with the Tar Heels through the 2014-15 season.

Williams, who signed an eight-year contract to coach his alma mater before the 2003-04 season, will make up to $1.8 million each year plus incentives based on the Tar Heels' performance on the court and in the classroom.

"Roy Williams is the most complete coach in the country," athletic director Dick Baddour said. "I knew when we hired him he was an outstanding basketball coach, but he has also exceeded our every expectation in the manner in which he runs a basketball program. He believes in character first, he coaches for all the right reasons and he is a first-rate ambassador of our university."
