Schefter: O'Brien top candidate at Penn St.

Patriots offensive coordinator Bill O'Brien has emerged as "a leading candidate, if not the leading candidate," for Penn State's head coaching vacancy, ESPN NFL Insider Adam Schefter reports.

Meanwhile, the USA Today's Jonny Saraceno reports, citing a person with knowledge of the situation, that "only contract details need to be finalized before O'Brien is the man."

On Saturday, ESPN college football reporter Joe Schad reported, citing two sources, that O'Brien is a candidate for the Penn State job if it is turned down by Tennessee Titans head coach Mike Munchak.

O'Brien is in his first season as the Patriots' offensive coordinator, following two seasons as their quarterback coach and offensive play-caller. His contract expires following the 2011 season.

In his fifth season in New England, O'Brien also has college coaching experience, including a stint as assistant head coach/offensive coordinator at Georgia Tech.
