CHAPEL HILL – Boston College junior Reggie Jackson’s potentially game-winning 3-pointer came so close to falling Saturday that he believed – half joking, of course -- that North Carolina must have tightened the screws on the rim.
Instead, the 19th-ranked Tar Heels tightened the screws on their defense.
UNC overcame a double-digit comeback attempt by the Eagles, and its worst-ever scoring output in 361 games at the Smith Center , to win 48-46. The Tar Heels prevailed because they held BC to 26.9 percent shooting, dominated the backboards, and got a fortuitous defensive play from 6-feet-10 forward John Henson, who was guarding the 6-3 Jackson’s shot with scant seconds left.

DURHAM – Following Duke’s only loss of the season on Jan. 12 at Florida State, the Blue Devils resolved that they weren’t going to force seniors Nolan Smith and Kyle Singler to carry such a heavy load.
CHESNUT HILL, Mass. — Boston College changed coaches and styles since the last time N.C. State saw the Eagles last March. With a new reliance on the 3-point shot, the Eagles are different team and 3-0 in the ACC after a 75-66 home win over the Wolfpack on Tuesday night.
