The Nittany Lions, who open conference play against Notre Dame this weekend, have split both two-game series this season.
The ranking comes after the Nittany Lions' 33-24 victory over Indiana Saturday in Beaver Stadium.
Allar tossed three touchdowns and 210 yards in the 33-24 win.
The Nittany Lions survived Indiana's upset bid with Drew Allar's massive 57-yard fourth quarter touchdown.
Poor offensive execution and defense handed the Nittany Lions a 6-5 loss.
The Hoosiers have not won a Big Ten game yet this season.
