Jeff Capel can empathize with Austin Rivers' emotions

As Austin Rivers comes down from his adrenaline rush of a Wednesday night, the person who may have the best idea of how Rivers' one shot will affect his Duke legacy is Jeff Capel.

It's conceivable that Rivers' game-winning 3-pointer was the Blue Devils' most memorable shot in the series with North Carolina since Capel hit a running 30-footer at the end of the first overtime of the teams' Feb. 2, 1995 game.

There are differences between the two buzzer-beaters, with the most notable being that Capel's effort didn't win the game for Duke - North Carolina ended up outlasting Duke 102-100 in double overtime.

So in that sense, Rivers' heroics were even more magical for the Blue Devils.

"It's something that he'll be able to tell his kids about it," said Capel, who is now an assistant coach for the Blue Devils. "It's something that his team will always remember, too - everyone that was associated with it.

"The game will probably be known as the 'Rivers shot.' "

The Capel shot game has taken on a life of its own and become something of an urban legend. Many people, Capel said, have only seen highlights of his shot and do not realize it only tied the game.

That doesn't bother Capel so much as the final score still irritates. With Mike Krzyzewski on leave with an ailing back, that was the season everything went wrong for the Blue Devils. In some ways, the loss to UNC encapsulated the entire season.

"It would have meant more to me and would mean more to me know if we would have won the game, especially if that would have been the game-winner," Capel said.

Nonetheless, Capel enjoys his place in Duke-North Carolina lore.

Capel said he still gets asked about the shot - with the Tar Heels up three, Serge Zwikker missed a free throw before Cherokee Parks rebounded the ball and passed it to Capel, who dribbled twice and took two steps before letting fly from a spot halfway between the top of the 3-point arc and the half-court line - all the time.

"For a kid that really understands this rivalry, to have a moment that will always be remembered in this historic rivalry - it's something that's very special to me," Capel said. "I know Austin didn't grow up in this state, but Austin's a student of the game. I know it's always going to mean something to him and for him to always have a moment like that.

"He'll always have this moment and it's always something that people will remember and identify him with. Hopefully, there are many moments like that for him. But certainly around here and in college basketball, people will always remember that."

Duke-UNC: Three keys for Devils in tonight's ACC clash

Duke's problems with consistency and intensity were on display in its 78-74 overtime loss to Miami on Sunday, when the Blue Devils fell behind by double digits in the first half against the Hurricanes and couldn't quite come all the way back for the victory.

It would be a surprise if either was an issue tonight against the Tar Heels.

In a sense, the rivalry game comes at a perfect time for the No. 10 Blue Devils (19-4, 6-2), who have needed multiple shots in the arm this season. With UNC on the docket, motivation shouldn't be an issue.

Of course, there's the question of the team's confidence after the loss to Miami. But the Blue Devils have proven to a pretty solid team this year when they're locked in. Assuming they don't misplace their motivation, here are three keys for tonight's game (9 p.m. WBTV, ESPN):

1. Win the Rivers vs. Barnes matchup

One would expect the two touted recruits would guard each other at some point of the festivities and perhaps for a majority of the time.

Harrison Barnes' height - he's 6-foot-8 - will certainly pose problems for the 6-foot-4 Austin Rivers. But Rivers speed could challenge the hobbled Barnes, who has said he will play despite the ankle injury he suffered against Maryland.

It's hard to see many paths to victory for Duke if this matchup breaks UNC's way in a decisive manner.

2. Wear down Kendall Marshall

In Marshall, UNC has one of the top point guards in the country.

In Tyler Thornton, Quinn Cook and Seth Curry, Duke has a point guard rotation that is dictated by the matchup and who is playing well. With Marshall not having much in the way of a serviceable backup, the Blue Devils' best hope will be to try and wear Marshall down as best they can.

Otherwise, Marshall's incisive passes into the post or to teammates in transition could be the death of the Blue Devils.

3. Come up with its defensive effort of the year

UNC and Duke lead the ACC in scoring offense. The problem for the Blue Devils is that the Tar Heels' defense (second in the ACC in field-goal percentage defense, and 14th in Ken Pomeroy's adjusted defense ranking) is significantly better than Duke's (last in the ACC in field-goal percentage defense and 91st in the KenPom rankings).

Duke has shown it can defend in stretches this season. Most of the time, those stretches have come after prolonged periods when opposing teams have had free reign to run their offense. But if the Blue Devils can pay attention to detail for 40 minutes, not get lost on screens and remember to help every time, perhaps they can flip this storyline.

If not, someone's going to have to hit a lot of 3-pointers.

Duke consistently talks about consistency

The watchword at Duke on Monday was "consistency," and no one -- not the players, not coach Mike Krzyzewski -- had an explanation why the Blue Devils have been so inconsistent this year. At least, they were consistent in that respect.

"I don't know, but we have to figure it out," Duke forward Mason Plumlee said, two days before Duke visits North Carolina in the first meeting between the teams.

"This is one of the most different teams I've had," Krzyzewski said. "Overall, they've done a good job, or we wouldn't be 19-4. But different guys have done well and we've done enough to win that many games. But I don't think anyone has had an exceptional year, or for the last month. Again, that doesn't mean they've been bad. That's not usually the case for our team. Usually, we have one or two guys who are all-ACC candidates."

There's no question Duke has players who are capable of playing at that level: Plumlee did it against Maryland. Andre Dawkins did it against Michigan State and Wake Forest. Austin Rivers did it against Miami. Seth Curry should probably do it more often, and Ryan Kelly presents significant matchup problems.

Yet none of them has said, "I'm the go-to guy. I want the ball in my hands right now," on a regular basis, although Rivers in recent days probably comes closest, and Krzyzewski said Plumlee has been Duke's most consistent player, particularly when it comes to rebounding.

"No question it's a different challenge," Krzyzewski said. "No question about that. Every coach would rather have two or three guys all the time, because then you can build better."

Perhaps the most baffling manifestation of Duke's inconsistency is at the defensive end, where defensive intensity has been a part of Duke's DNA for decades.

"It's something that we've shown flashes of being really good at," Kelly said. "I think it just comes down to being consistent, as individuals and as a team. We've improved in areas, and then not done as well in other areas. It has to be a true decision that we're going to be better defensively, and it has to be there every single day."
