Player Analysis:
(largely based on ratings above)

Duke supplies the All-American firepower in this matchup.  Williams and McRoberts have been thoroughly and efficiently dominant.  And most people would overlook Redick's lower rating here and say that he's one of the handful of candidates for Player of the Year.  So, no matter how you cut it, Duke's players are extremely talented, as their record would indicate.

North Carolina is not short on stars either.  Hansbrough has been a beast inside from the moment he stepped onto the court.  The freshman is rated even higher than Redick, which is impressive considering that Duke's superior team strength does give Redick an edge in the ratings.  Hansbrough is truly having a spectacular season.  Danny Green is no slouch either.  With good shooting and a surprising number of blocks, Green has been a surprising force for the young Tarheels.  His efficiency has been better than that of Terry and Noel, but because of less playing time, his overall contribution (cPSAN) is still lower than those two's.

Much heralded freshman Greg Paulus for Duke has shown he is very capable, but his rating here puts him last on the team.  Why?  Turnovers.  This is a bit complicated, but here's the gist.  Duke has an excellent points-per-possession rating.  So, the value of a possession is extremely high for them compared to most teams.  A turnover takes a possession away from them, which means that Paulus' high number of turnovers hurts him more than it would a player on a less efficient team.  Even though Paulus has a 1.6 AST:TO ratio, the overall contribution of his AST and TO is significantly negative because of what I just outlined.  No doubt, the kid has skills and will improve and be a star, but for now according to this ratings system, he's not contributing as well as his teammates. 

Efficiency Analysis

Duke

North Carolina

  • Duke plays at a brisk tempo (#47), with the nation's best offense and an elite defense (#9)
  • Duke's offense excels in all phases brilliantly except that they are a very poor offensive rebounding team (#265)
  • Duke excels in nearly every defensive phase as well, except allowing offensive rebounds (#238)
  • Duke is one of the nation's best blocking teams (#15) and doesn't get blocked often
  • Duke is one of the nation's best at not allowing assisted baskets
  • The freethrow line is owned by Duke, as they are #3 in using it as a weapon while keeping opponents from effectively using it (#8)

 

  • UNC plays at one of the fastest tempos in the country (#19) with an excellent offense (#35) and stifling defense (#19)
  • UNC's offense excels in every category except that they turn the ball over way too often (#297)
  • UNC's offense does a great job of assisting on most of its made baskets (#10)
  • On defense, UNC is excellent in most phases, with the only phase they could improve being forcing turnovers (#163)
Other Efficiency Notes:
  • Duke scores a disproportionately high percent of its points from the freethrow line but low percentage from 2FG, while on defense it is ridulous how much its opponents are forced to rely on 2FG's.
  • UNC is a much less extreme version of Duke in that they score a reasonably above-average percent of their points from the freethrow line, while opponents score an above-average percent of their points from 2FG's.

Game Outlook

Duke-UNC is always a good game.  To predict that one team will clearly win would be ludicrous.  The odds favor an up-and-down game with plenty of freethrows.  UNC will most likely pound it inside as Duke usually shuts down the perimeter game.  That means Hansbrough vs Williams will be the key matchup here.  If Hansbrough can get Williams into foul trouble, that will really open things up for UNC.  But their margin for error is slim because Redick will be firing 3FG's all night long.  The good news for UNC is that when the 3FG's miss, Duke doesn't usually get offensive rebounds, which means UNC will be running their fast break quite freely.

Also, expect there to be plenty of turnovers from UNC.  They're young, it's an emotional game, and there will be a lot of running.  But Paulus turns it over quite often himself.  The battle of backcourt turnovers may be another important key to this game.

My personal prediction: Duke wins 84-77.
