Something strange has happened with the Duke-North Carolina rivalry this season.
No, the intensity and fire didn't dissipate in the Tar Heels' thrilling 82-78 win in Chapel Hill in early February, but as we prepare for Saturday's rematch inside Cameron Indoor (8:15 p.m. ET, ESPN), we do so while scratching our heads to figure out who these two blue bloods really are.
In what is very rare to this bitter rivalry, No. 5 Duke (24-6, 12-5 ACC) and No. 9 North Carolina (22-8, 11-6) will face each other on the final weekend of the regular season as total mysteries to us -- and probably themselves.
