Not all teams begin a college football season clicking on all cylinders, punishing opponents in the trenches with their hulking bruisers and firing unreachable passes to their world-class speedsters at receiver.

Some teams explode out of the gate and never look back at the pack of wannabe contenders on their way to the College Football Playoff three months later. The 2021 season seems much different than the others in the playoff era, however. The elite have noticeable weaknesses and the wannabes suddenly look like could-bes in what is shaping up to be wild races across conferences and, ultimately, the four-team field at the end of the season.

Already we have seen our fair share of drama among the nation's best. Nineteen teams ranked in the AP poll have fallen, the most ever in the first three weeks of a season. Ohio State was shocked by Oregon at home. Alabama's offense slowed to a crawl as Florida mounted a comeback that sent the Tide scrambling for answers before ultimately hanging on for a two-point win in The Swamp. Clemson's offense, the pillar of college football over the last decade, suddenly looks pedestrian with a new quarterback at the helm.

And then there are those teams on the periphery, doing just enough to hang around and make it seem like anything is possible as the elite hang on to their precious spots, not knowing if their once-strong grasp on the sport will slip or tighten as conference games hit the schedule.

"You look across the country, you might have four or five teams that are playing exceptionally well right now, and most everybody else is essentially beating themselves," Oklahoma State coach Mike Gundy said Saturday. "If you can avoid beating yourself, it gives you a chance in most games."

That was once only the case for the wannabes and those teams on the periphery. Now, in 2021, with Super Seniors on rosters across the country and an influx of new quarterbacks, it seems anything is possible. Still, with a quarter of the season already expired, we can more easily identify the true contenders and pretenders in the playoff race.
