Georgia fans have had months to stew over a certain 2nd-and-26 play.

Their overtime heartbreak, when Alabama converted for the game-ending touchdown to defeat the Bulldogs in last season’s College Football Playoff Championship Game, will long live in the sport’s lore.

But Oklahoma fans had their own Playoff overtime bummer to deal with all summer.

The Sooners so nearly broke up the all-SEC Playoff party in January’s Rose Bowl. Oklahoma led 31-14 in the first half and 45-38 with about a minute left in regulation, but the Bulldogs kept coming back. Sony Michel’s 27-yard walkoff touchdown run in the second OT left Sooners quarterback and Heisman Trophy winner Baker Mayfield standing on the sidelines, with his hands on his knees in disbelief.

The gang in Norman is going to miss the No. 1 overall NFL Draft pick, obviously. Mayfield, who started his college career at conference rival Texas Tech, broke just about every passing record there was to break at Oklahoma.

Now fellow transfer Kyler Murray (remember him, Aggies fans?) is battling sophomore Austin Kendall for time behind center. Murray is a junior, but this is supposed to be his last year of football; that was the deal that MLB’s Oakland Athletics made with him after they selected him ninth overall in this summer’s entry draft.

But until somebody else proves otherwise, Oklahoma is still the team to beat in the Big 12. And that makes the Sooners a threat to the SEC in the 2018 College Football Playoff race.

Yes, they lost not only Mayfield but two other All-Americans on offense, tackle Orlando Brown and tight end Mark Andrews. But the Sooners have been in reload mode for more than a decade, and didn’t seem to miss a beat in 2017 under new coach Lincoln Riley.

The Big 12 has only earned two CFP semifinal bids in four years under the 4-team Playoff system. Guess which school earned both bids?

Plus Oklahoma still has a lot of weapons on offense.

Running back Rodney Anderson, a junior, rushed for 100 or more yards in six of Oklahoma’s final eight games last season, including 201 yards against Georgia in Pasadena and 151 against the Big 12’s best defense (by a mile), TCU.

The Sooners return a deep group of wide receivers including Marquise Brown (1,095 yards and 7 touchdowns receiving last season) and CeeDee Lamb (807, 7).

Oklahoma ranked 87th in the nation in passing defense in 2017, third in the Big 12.

There are questions on defense, but the amount of turnover (only five starters return) might not be so bad for a unit that ranked 67th in the nation in 2017. Five of Riley’s top seven recruits signed in the Class of 2018 are on the defensive side of the ball, including 4-star cornerback prospect Brendan Radley-Hiles, who is expected to start right away.

The schedule is relatively kind to the Sooners as well — the finale at West Virginia and the neutral-site game against Texas in Dallas are likely to be the two toughest tests.

If the Sooners can get it together on defense and navigate those hurdles plus the Big 12 championship game, the Big 12’s flagship program might be in a position to bust up the SEC’s championship dreams.
