FOXBOROUGH, Mass. — Bill O’Brien wore a cap with a Patriots logo as he prepared his players for Sunday’s AFC championship game.

New England’s offensive coordinator would like to keep wearing it for a couple of weeks — through the Super Bowl — before switching to a Penn State hat in his next job as head coach of the Nittany Lions.

For now, he’s preparing his offense to face the dominant defense of the Baltimore Ravens.

“We’re definitely all focused on the game with Baltimore and that’s what our team is preparing for,” coach Bill Belichick said Thursday. “He’s done what we’ve asked him to do last week and this week and, hopefully, we’ll be able to play well on Sunday.”

On Jan. 8, shortly after the Denver Broncos beat the Pittsburgh Steelers 29-23 in overtime to advance to the divisional game in Foxborough, the Patriots announced they had hired Josh McDaniels as an offensive assistant.

He was the Patriots’ offensive coordinator from 2006-08, served as Denver’s coach in 2009 and was offensive coordinator of the Rams this season.

“Josh has integrated very smoothly into everything that we do because he knows most everybody here,” quarterback Tom Brady said. “He knows the offense. His input is greatly appreciated, whether it’s tips for me or tips for other players. He sees some things. It’s been good.”

On Thursday, O’Brien talked with Brady and other players at practice while members of his new staff focused on recruiting. Seven of his Penn State assistants are on the road at one time and he makes recruiting calls himself.

National signing day is Feb. 1.

“We’re certainly making the best of it we possibly can,” offensive line coach Mac McWorter said. “You certainly have to commend coach O’Brien for finishing his obligations to New England. That says a lot about the way he does things.”
