Quinn Cook of Mouth of Wilson (Va.) Oak Hill signed with Duke on Thursday.

Cook played at famed Hyattsville (Md.) DeMatha in 2009-10, but transferred to equally famous Oak Hill for his senior season.

"Quinn is a pass first point guard," said Oak Hill coach Steve Smith. "He can really shoot it and has very good three-point range. A lot of point guards who can shoot it, look for their shot all the time, but Quinn wants to get everyone involved in the offense."

Cook also considered signing with UCLA.

Cook will join Austin Rivers in Duke's 11-12 backcourt. Duke could also have Kyrie Irving if he doesn't leave for the NBA after his freshman season.

Harrison Barnes of North Carolina became the first freshman named to the preseason All-America team since voting began in 1986.

Barnes was joined by Kyle Singler of Duke, Kansas State's Jacob Pullen, BYU's Jimmer Fredette and Purdue's JuJuan Johnson.
