What a difference one week makes.

Upsets were plentiful on the opening weekend of the high school football season; four of the state’s top-ranked teams each lost their season openers, causing quite a shakeup in the Louisiana Sports Writers Association’s rankings.

Defending Class 5A champion Acadiana earned a unanimous No. 1 ranking after West Monroe suffered its first loss to C.E. Byrd since 2002. A 38-7 setback against 5A St. Paul’s dropped Edna Karr from the top spot in 4A, making room for St. Thomas More, which also claimed all 11 first-place votes.

St. Charles Catholic climbed to No. 1 in Class 3A after Parkview Baptist fell to 5A Mandeville 19-16, while John Curtis Christian rose to the top of Class 2A after Evangel fell 21-0 to Union High School (Okla.).

Defending 1A champion White Castle retained its top ranking after a 25-0 win against Glen Oaks, but Bulldogs coach Ferrante Dominique said his team must remain focused on improving in all phases of the game to avoid a similar fate.

“No matter where we’re ranked, we have to work to where we feel like we’re the best team that gets on the field every week and continue with that attitude,” he said.

Among local teams, perhaps the biggest beneficiary of the wild weekend was Dutchtown.

The Griffins moved from fourth to second in Class 5A after a 32-8 triumph over Lutcher led by senior safety running back Landon Collins, who finished with 94 rushing yards, one touchdown and one interception.

Like most coaches, Dutchtown head coach Benny Saia welcomes the honor, but realizes the recognition also comes with a target.

“It’s much better to be the hunter than the hunted,” he said. “When you’re ranked that high up there it certainly gives the other team some incentive to get after you.”

Also rising up the rankings was University. The Cubs opened their season in New Orleans with a 27-6 victory against Newman to jump from sixth to fourth in Class 2A.

“I’d love to be ranked that high at the end of the year, but it is what it is right now,” said University coach Chad Mahaffey. “It’s certainly an honor and something we’re striving for, to be a top program in 2A.

“But we’ve got some tough teams on our schedule so we have to make sure they get our best shot.”

A pair of local teams cracked the top 10 in their respective classes after opening the season with impressive victories.

St. John of Plaquemine debuted at No. 10 in Class 1A after rushing for more than 450 yards in a 51-22 win over 4A Belaire, and Episcopal was ranked No. 10 in Class 2A after opening its season on the road with a 36-0 win against Albany.

Episcopal coach Travis Bourgeois said with the ranking comes responsibilities and expectations his players must handle for the duration of the season.

“It’s good recognition for your program, but at the same time, whenever you make the top 10 everyone across the state knows who you are,” Bourgeois said.

“There’s no sneaking up on anybody.”
