In Williams' first season, the Tar Heels finished 19–11 and were ranked in a final media poll for the first time in three years. They returned to the NCAA tournament and were ousted in the second round by Texas. The following year, the Tar Heels won their fourth NCAA title and Williams' first as a head coach. After winning the championship, Williams lost his top seven scorers, but the 2005–06 season saw the arrival of freshman Tyler Hansbrough and Williams was named Coach of the Year. The Tar Heels swept the ACC regular season and tournament titles in 2007 and 2008. The 2008 ACC Tournament was the first time North Carolina has ever won the ACC Tournament without defeating at least one in-state rival during the tournament. North Carolina lost in the national semifinals of the 2008 NCAA tournament to Williams' former program Kansas.
In 2015-2016, led by seniors Marcus Paige and Brice Johnson, the Tar Heels earned their 30th ACC regular season title, 18th ACC tournament title, and 19th Final Four.[circular reference] They also appeared in their 10th NCAA title game, in which they lost on a buzzer beater to Villanova, despite Marcus Paige's dramatic three-pointer to tie the game with 4.7 seconds left.[circular reference] The Tar Heels finished with a 33-7 overall record and a 14-4 ACC record.
The Tar Heels own several notable streaks in the history of college basketball. They appeared in either the NCAA Tournament or National Invitation Tournament (NIT) every year from 1967 to 2001. This includes 27 straight appearances in the NCAA tourney from 1975 (the first year that competition allowed more than one team from a conference to get a guaranteed bid) to 2001—the longest such streak in tournament history until it was broken by Kansas in March 2017. The Tar Heels also notched 37 straight winning seasons from 1964 to 2001, the third-longest such streak in NCAA history, behind UCLA's streak of 54 consecutive winning seasons from 1948 to 2001, and Syracuse's currently active streak of 46 seasons from 1971 to date. They also finished .500 or better for 39 years in a row from 1962 (Dean Smith's second year) to 2001, the third-longest such streak in NCAA history, behind Kentucky's streak of 61 consecutive seasons from 1926 to 1988 (the Wildcats were barred from playing in 1952–53 due to NCAA violations) and UCLA's 54-season streak.
Additionally, four of the top eight and six of the top 30 winningest programs in NCAA Division I basketball history currently reside in the ACC. Three of the six active Division I coaches currently in the Naismith Basketball Hall of Fame are competing in the ACC again this season – Duke’s Mike Krzyzewski, North Carolina’s Roy Williams and Syracuse’s Jim Boeheim.
