The first College Football Playoff rankings of the season has the Ohio State Buckeyes debuting at No. 1 and defending national champion Clemson on the outside looking in at No. 5.
The Buckeyes are followed by No. 2 LSU and No. 3 Alabama, who have been ranked either first or second in the AP Poll for the last four weeks and will face each other in a blockbuster matchup on Saturday in Tuscaloosa.
Penn State rounds out the top four, leapfrogging Clemson -- who was ranked fourth in the AP Poll.
