OL David Harding (6-5 285) of Orlando committed to Duke over USC Tuesday according to his coach. Harding made an unofficial visit to USC last weekend. Harding is an honors student, and Duke's academic appeal was a major reason for his decision. "He said he felt comfortable with the academics and with how coach Cutcliff talked to him," coach Phil Siglar said. Harding had 17 offers and narrowed his decision to Duke, USC and Central Florida.
