MEMPHIS, Tenn. (WTVD) -- North Carolina expects strong offensive performances from junior leaders Justin Jackson and Joel Berry II, but Luke Maye provided an unexpected bonus.
Berry scored 26 points, Jackson had 24, but it was the first career double-double from Maye - 16 points and 12 rebounds - that helped set the tone early and send the top-seeded Tar Heels to a 92-80 victory over Butler in the NCAA tournament on Friday night.
"He has the ability to shoot the ball. He has the ability to rebound the ball," North Carolina coach Roy Williams said of the sophomore forward and former walk-on. "But the reason Luke is going to be successful is what he's got in his brain and in his heart."

Carolina, which reached the Elite Eight for the 27th time, will face Kentucky, which beat UCLA 86-75 in the second South Regional.
Kentucky defeated North Carolina earlier this season.
Maye's early jolt off the bench helped Carolina (30-7) build a first-half lead to as many as 20 as the Tar Heels benefitted from accuracy, connecting on 54.4 percent of their shots while Butler was at 43.5 percent.
"We knew we were going to have to make some perimeter shots to give ourselves a chance," Butler coach Chris Holtmann said. "They were going to give us some clean looks, and we were going to have to make them. We just didn't."
Andrew Chrabascz led the fourth-seeded Bulldogs (25-9) with 21 points and seven rebounds, while Kelan Martin finished with 16 points for Butler, which struggled shooting early and did not recover.
"We let them get into a rhythm, especially in the beginning," Chrabascz said. "When you let a team like that feel good about themselves, it's tough to get them out of that with how many talented guys they have on their team. And also they answered every run that we had."
The Tar Heels broke out of the gate early, building a double-digit lead and really weren't threatened after halftime, although Butler did get within 10 at one point. Carolina, which let Arkansas claw back before defeating the Razorbacks 72-65 last weekend, weren't going to let that happen again.
"We got by with very little room against Arkansas," Jackson said. "We knew it was a game of runs. Butler is a good team, and they keep on coming at you. For us, we tried to stay focused and stay poised."
North Carolina used early accurate shooting to build a 16-point lead as the Tar Heels connected on 13 of their first 18 shots, including missing only one of seven from outside the arc.
While Butler managed to whittle the deficit to single digits on a couple of occasions before halftime, North Carolina would simply answer with another rally, helping the Tar Heels carry a 52-36 lead into the break.
The Tar Heels lead would stretch the lead back to 20 near the 12-minute mark of the second half, but Butler didn't exactly allow North Carolina to coast home.
A 13-4 Bulldog run made a dent in the advantage as Martin had seven in the stretch with Avery Woodson connecting on a 3-pointer. Martin closed out the run with another 3-pointer to pull Butler within 71-60.
But while the Bulldogs would cut the Carolina advantage to 10 points 2 minutes later, they would get no closer the rest of the way.
The Bulldogs had not trailed in the tournament until Carolina's Isaiah Hicks scored the game's opening basket. The two previous times Butler defeated a No. 1 seed, the Bulldogs went all the way to the national championship game.
The Tar Heels have reached the Elite Eight 27 times, including eight times since 2000. Maye's 16 points were a career-high. "I got a couple of shots to fall in and felt pretty confident they kept going in," Maye said.
Kentucky 86, UCLA 75.
De'Aaron Fox scored a career-high 39 points as the Kentucky Wildcats beat UCLA 86-75 Friday night in a showdown between two of college basketball's goliaths for a spot in the South Regional final.
The only No. 2 seed to survive and advance, the Wildcats (32-5) won their 14th straight game. Now the NCAA's winningest program will play another of basketball's titans Sunday in top-seeded North Carolina with a trip to yet another Final Four on the line.
The third-seeded Bruins (31-5) still have the most national titles. Yet they leave their third Sweet 16 under coach Steve Alford short of the Elite Eight.
Fans lustily booed Kentucky coach John Calipari in his first game in Memphis since leaving in April 2009 for the Wildcats. Calipari's latest crop of talented freshmen put Kentucky into a regional final for the sixth time in seven years.
