The Post’s Howie Kussoy breaks down the Peach Bowl (Saturday, 4 p.m., ESPN) between LSU and Clemson.

The Tigers spent most of the decade held back by their offense. Now, it has propelled them to the No. 1 team in the nation. Playing in their new spread attack, Heisman Trophy winner Joe Burrow led the top-ranked total offense to 47.8 points per game, while setting the sport’s all-time completion percentage mark (77.9) and throwing for more than 362 yards per game, with three receivers recording double-digit touchdowns. All-SEC First Team running back Clyde Edwards-Helaire, who has a hamstring injury, will be a game-time decision, but the presence of Burrow and the nation’s best offensive line should allow any of their talented backs to break off big runs. Oklahoma’s first-year defensive coordinator, Alex Grinch, rebuilt one of the most embarrassing units in college football into one of the Big 12’s best, but even acclaimed SEC defenses like Georgia and Florida were decimated by the Tigers’ unstoppable offense. The absence of Oklahoma’s top pass-rusher, Ronnie Perkins (suspension), and safety Delarrin Turner-Yell (broken collarbone) further dim the Sooners’ hopes of slowing Burrow, who has been at his best in the season’s biggest moments.

Edge: LSU

After back-to-back years bringing the Heisman winner to the playoff (Baker Mayfield, Kyler Murray), the Sooners had to settle for having the runner-up. Former Alabama star Jalen Hurts brings unparalleled experience into his fourth straight playoff, and he is the most dangerous dual-threat the Tigers have faced all season. Hurts, who leads the nation with 11.8 yards per pass attempt, and has a 71.8 completion percentage, is also the Sooners’ leading rusher, with 1,255 yards and 18 scores on the ground. Oklahoma, which leads the nation with 8.2 yards per play and averages 43.2 points per game, also gets 6.7 yards per carry from running back Kennedy Brooks. Though the Tigers have the most talented secondary in the country — safety Grant Delpit and cornerback Kristian Fulton will be first-round picks this spring — and have allowed a total of 17 points in their past two games, the defense has been responsible for the team’s tensest outings. Alabama’s Tua Tagovailoa threw for 418 yards against them. Sam Ehlinger of Texas threw for 401 yards. Dual-threat John Rhys Plumlee of Mississippi ran for 212 yards and four touchdowns. Hurts can beat them either way.

Edge: Oklahoma

With such powerful offenses, neither side may need to — or be willing to — punt. Neither side has done much damage in the return games. Defenses will claim victory upon forcing field-goal attempts. Oklahoma’s Gabe Brkic won the job in late September and produced the country’s first perfect season by a kicker — with more than 12 attempts — in six years, hitting all 17 field goals and all 48 extra-points. LSU freshman Cade York is perfect from inside 40 yards (12-for-12) and 9-for-13 from deeper, while sharing a national lead with four makes of at least 50 yards. He has, however, missed four extra points.

Edge: Oklahoma

Ed Orgeron, 58, has redefined his career in four months. The coach, who was canned after three losing seasons at Ole Miss and deemed unfit to lead USC, is barely a year removed from answering questions about his job security, but his hiring of 30-year-old passing game coordinator Joe Brady elevated a staff that had repeatedly fallen short of expectations. Orgeron gained national championship experience eons ago at Miami and USC, but has never been in charge for a true postseason game. Lincoln Riley, 36, may not have the best offense in this game, but still possesses perhaps the brightest offensive mind in the sport. Oklahoma has reached the playoff in each of Riley’s three seasons in charge — and has been in four semifinals in five seasons with him on staff — but the Sooners are still searching for their first national championship appearance since 2008.

Edge: Oklahoma

Aside from the quarterbacks, who finished 1-2 in the Heisman Trophy voting, here are three other players who could determine which team takes the Peach Bowl:

Ja’Marr Chase, LSU, WR

Named the school’s second-ever winner of the Biletnikoff Award — given to the nation’s best wide receiver —the 6-foot-1 sophomore led the nation with 1,498 yards and 18 touchdowns in the regular season. The explosive wideout has scored in all but two games this season.

CeeDee Lamb, Oklahoma, WR

The Biletnikoff finalist and likely top-10 NFL pick averages 20.8 yards per catch and is the Sooners’ only receiver with more than five touchdown receptions (14), but he’s also had three games with fewer than four catches. In last year’s playoff loss to Alabama, Lamb had eight receptions for 109 yards and a touchdown.

Derek Stingley Jr., LSU, CB

If Lamb is a non-factor, the Tigers’ true-freshman phenom likely will be why. The consensus All-American ranked second in the nation with 15 passes broken up and led the SEC with six interceptions. Two picks came in the SEC Championship against Georgia’s Jake Fromm, who hadn’t been intercepted in six games.

Prediction

The Sooners benefit from having reached previous playoffs. Their quarterback has been in more big games than most players in the sport’s history. Their rushing game — fourth in the nation, averaging more than six yards per carry — is capable of keeping Burrow off the field for long stretches. But when the Tigers take the field, Oklahoma has no chance to accomplish what elite SEC defenses failed to do. The Tigers have too much talent to be stopped. Hurts will be phenomenal, but Burrow will be even better, just as he has been throughout his dream season.
