DURHAM, N.C. - Kendall Marshall felt dissed by Duke. The Blue Devils played the highlights of their last-second win over North Carolina on the video scoreboard and Marshall didn't like it, so he brought his Tar Heels into a quick huddle.
"I told my teammates I thought that was disrespectful, and we need to go out here and prove a point," Marshall said.
Did they ever.
North Carolina never trailed in an 88-70 rout of No. 4 Duke on Saturday night, claiming the Atlantic Coast Conference regular-season title behind 20 points and 10 assists from its motivated point guard.
"It left a bad taste in our mouths," Marshall said, "and we wanted to be able to come out and play well today."
Tyler Zeller had 19 points and 10 rebounds, and Harrison Barnes added 16 points for the Tar Heels (27-4, 14-2). For the second straight year, they rolled in a winner-take-all season finale with the ACC tournament's top seed - and possibly one in the NCAA tournament, too - on the line.
"My team's had some bounce-back to them all year long," North Carolina coach Roy Williams said. "We go down to Florida State and lose by 3 million and everybody's jumping off the bandwagon ... but our team kept playing. We lose to Duke and everybody's got a great opinion of how stupid we are ... (and) my team kept playing."
North Carolina shot 54.5 percent, built a 45-28 rebounding advantage and sent Duke to its deepest halftime deficit ever at Cameron Indoor Stadium - 24 points - while winning its seventh straight since last month's loss to the Blue Devils.
Mason Plumlee had 17 points, and brother Miles Plumlee added 16 points and 11 rebounds in his final home game for the Blue Devils (26-5, 13-3). Freshman guard Austin Rivers - the hero of that last meeting - had 15 points.
But Duke - which erased a 10-point deficit in the final 2 1/2 minutes to win the first matchup, then rallied from 20 down in the second half to beat North Carolina State - couldn't come up with another improbable escape and instead had its seven-game winning streak snapped.
"Throughout the year, we've been immature. We always want to see how little we have to do to win," Miles Plumlee said. "You give a team like that a 20-point lead, it's nearly impossible to win. We need to fight, like we did at times, for a whole game."
Duke was trying for its second regular-season sweep of North Carolina in three years, after the Blue Devils won the dramatic first meeting in Chapel Hill. They hit 14 3-pointers in that game - none bigger than Rivers' buzzer-beater that punctuated the 85-84 win.
For too long in this one, those shots didn't fall.
The perimeter-reliant Blue Devils finished 6 of 21 from 3-point range. They missed 15 consecutive shots, including their first seven 3s, and had two 7-minute field goal droughts in the opening half. That left them down 48-24 at the break - their largest halftime deficit anywhere since the 1990 team trailed the Tar Heels by 24 in Chapel Hill.
"When you base, like we do, a lot of our offense on 3-point shooting ... some will say, `Don't.' That's who we are, man," Duke coach Mike Krzyzewski said. "And if we're not hitting them, we have a much greater chance to lose."
