Landry-Walker played the 20th game of the school’s brief history on Friday night.

None of the previous 19 were bigger than this one.

Landry-Walker staked its claim to Algiers bragging rights in convincing fashion with an easier-than-expected 27-7 victory over rival Karr at Behrmen Stadium.

“This shows that we own the city,” sophomore quarterback Keytaon Thompson said.

Landry-Walker, which formed last season when Landry High and O. Perry Walker merged, improved to 5-1 overall and 1-0 in District 9-4A.

In the process, the Charging Buccaneers snatched bragging Westbank bragging rights away from Karr, which last lost to O. Perry Walker in 2007.

Karr had defeated O. Perry Walker or Landry-Walker seven straight times, including twice last season.

Thompson, who was just 8-years-old the last time O.Perry Walker bear Karr, accounted for three touchdowns, and the defense did the rest.

Karr’s lone touchdown came with just 55 seconds left, when Aldon Clark connected with Kenneth Simmons on a 20-yard touchdown to avoid the shutout.

But it was way too little, and way too late.

Landry-Walker, ranked No. 3 in the Louisiana Sports Writers Association 4A poll and No. 4 in The New Orleans Advocate’s Large School Super 10, owned this one from the start.

“It’s my senior year, and we had never beat Karr,” said Landry-Walker defensive back Marquis Green, who had a pair of interceptions. “I’m not surprised we dominated. We knew we had the players to do it if we came out and played two halves. This is the greatest win I have been a part of. We wanted to do it for all the alumni and for the team.”

It didn’t take the Charging Bucs long.

Tevin Bush ran for a 10-yard score, hurdling a defender at the goal line to give the Charging Buccaneers a 7-0 lead in the first quarter.

Thompson led the Charging Buccaneers to two more first-half touchdowns.

He first scored on a 37-yard run, then connected with Kaleb Anderson on an 18-yard touchdown to give Landry-Walker a 20-0- lead with 2:31 left in the first half.

The Landry-Walker defense was stellar in the first half, forcing three turnovers (two fumbles and an interception) and holding the Cougars to just 51 yards in the first two quarters (43 rushing, 8 passing).

Karr had just 158 yards of offense in the game.

“The defense played outstanding,” said Landry-Walker coach Emanuel Powell. “The offense didn’t play bad. We just have to cut down on penalties.”

Powell’s team was penalized 15 times for 132 yards, but that was about all that went wrong on this night before an overflow crowd at Behrman Stadium.

Karr (2-3, 0-1), ranked No. 8 in 4A and No. 8 in Super 10, didn’t do much to help itself. The Cougars finished with six turnovers (four fumbles and the two interceptions.)

“It’s about the process,” Karr coach Nathaniel Jones said. “We didn’t practice well on Monday. Credit Landry-Walker. We did a poor job of protecting the football. I wish we had played better. I wish we had protected the ball better. But that’s all wishful thinking, and that’s all behind us now. We just have to go back and get better.”

Thompson scored on a 5-yard run in the fourth quarter that gave Landry-Walker a commanding 27-0 lead. He finished with 117 yards on 13 carries and completed 5-of-8 passes for 41 yards.

“They ended our season last year,” Thompson said. “We had that on our mind, and we wanted to get them back. So this means a lot.”

Powell was pleased with the win but wants to see his team clean up on the turnovers.

“It shows that we are here,” he said. “But it also shows we have a long ways to go.”
