Will O'Brien be pulling double duty?

According to ESPN's Adam Schefter, Bill O'Brien will continue as offensive coordinator with the Patriots through the playoffs. So does that mean he will be pulling double duty with both the Patriots and in his new role as head coach at Penn State?

ESPN's Chris Mortensen was asked that question on SportsCenter tonight (video above). He referred to the arrangement the last time this happened in New England, when then-offensive coordinator Charlie Weis was hired by Notre Dame in December 2004:

"That was the Patriots' last Super Bowl championship, that run was done after Weis was named the Notre Dame coach and he continued to do his job as [Patriots] offensive coordinator," Mortensen said. "I talked with Tedy Bruschi, who was on those teams, about that today and he said Charlie did his job like he normally did and maybe on his lunch break, or if he got a break here and there, he'd be making recruiting calls [for Notre Dame]. I'm sure some similar arrangement will be made for O'Brien. ...

"I'm assuming the Charlie Weis model from 2004 works because it did work. They won a Super Bowl even though he had the double duties."
