North Carolina enhances offense this season with 3-pointers

 For as long as Roy Williams has been at North Carolina, the Tar Heels have been famous for winning games on the interior.
UNC has long excelled at pounding the ball inside and crashing the offensive glass on any misses. It's an approach that has netted Williams two national championships at Chapel Hill, and, if not for a rather famous shot by Villanova's Kris Jenkins last April, it's possible that number would be three. This is most definitely a proven approach.
This season, however, Carolina is showing opponents a new look. The Heels are shooting more 3s than they ever have before under Williams. In ACC play, 33 percent of UNC's shot attempts have been launched from beyond the arc. By comparison, the program's 13-year average under Williams heading into this season was just 26 percent in conference play.
In fact, as recently as the 2014-15 ACC season, North Carolina devoted just 20 percent of its shots to 3-point attempts. This season therefore marks a decided change in direction for the Heels' offense. The 3-pointer used to be this team's choice on one out of every four or even five shots. Now it's one in three.
