Tom Allen wore a weary smile in Penn State's locker room after the Orange Bowl as he surveyed a silent, still group of players hurting over the Nittany Lions' 27-24 loss to Notre Dame. Penn State's defensive coordinator, at least for that moment, tried to find context.

Penn State has officially lost its defensive coordinator. Tom Allen, after one just season with the Nittany Lions, was formally named Clemson’s new defensive coordinator on Tuesday afternoon.

Clemson has hired Penn State defensive coordinator Tom Allen for the same role with the Tigers. The move was finalized Tuesday by the school’s Board of Trustees Compensation Committee.
