still unbeaten after a 42-21 win against No. 12 Mississippi that was more dominant than the score suggests?
Or is it powerful Georgia, which destroyed No. 11 Arkansas 37-0 and has the nation’s best defense in nearly every major category?
After one week of October, these two teams are unquestionably at the front of the pack in the Football Bowl Subdivision and miles ahead of the other primary contenders for the College Football Playoff.
Several teams that even flirted with No. 1 consideration, whether in the preseason or in the weeks since, have either lost or failed to look the part of the best team in college football.
Ohio State struggled with Minnesota and lost to Oregon, though the Buckeyes have played much better in the past three weeks. Previously No. 3 in the Coaches Poll, the Ducks lost in overtime to Stanford and will plummet down the rankings. Oklahoma has remained unbeaten but has yet to resemble the teams that reached the playoff in three of the past four seasons.
WINNERS, LOSERS: Kentucky, Tennessee surprise; Wisconsin, Texas AM lose again
OPINION: How Lane Kiffin blew it against Alabama
Alabama has been No. 1 since the initial Top 25 and hasn’t necessarily done anything to be removed from that perch, even if the typically powerful running game struggled for much of September and the Crimson Tide barely escaped with a 31-29 win at Florida.
With so many losses from last year’s offense, the Tide have leaned on sophomore quarterback Bryce Young, who has tossed 17 touchdowns against just two interceptions.
Ranked fifth in the preseason poll, Georgia rose to No. 2 behind a smothering performance in the opener against Clemson and a series of blowouts in SEC play. The Bulldogs have outscored Arkansas, Vanderbilt and South Carolina by a score of 143-13.
It’s the defense that makes Georgia so dangerous. This group has given up just 23 points in five games and just a field goal in eight quarters against ranked competition.
Boiled down, these are the arguments for putting each team No. 1:
The only sure thing? That everyone else is chasing the Bulldogs and Crimson Tide. Deciding which team deserves to be No. 1 might be impossible until they meet in the SEC championship game on the first Saturday in December.
