The Big Ten's blue bloods are back. Despite new coaches at both Ohio State and Penn State, and a shaky start at Michigan, the Big Ten's three top traditional powers occupy the top spots in the power rankings as the season approaches its halfway point. Ohio State has accelerated its learning curve under Urban Meyer, while Penn State continues its hot streak behind boss Bill O'Brien. Michigan needed a strong performance on the road and got a great one at Purdue. Michigan and Penn State both make moves up the rankings, while Ohio State holds steady at No. 1.
