You’ve heard the saying that the Westbank is the Best Bank.

The city of New Orleans will need that to be true this weekeed to keep a certain streak alive.

Since 2011, at least one team from the Greater New Orleans area has won a state football state championship.

It’s up to either Edna Karr or John Ehret to keep that streak going this year, following the footsteps of Jesuit (2014), John Curtis, East Jefferson and Rummel (2013), Karr, Curtis and Rummel (2012), and Curtis in 2011.

Karr and Ehret will look to bring a state championship trophy from the Mercedes-Benz Superdome back across the Crescent City Connection on Saturday.

Karr will play Neville for the Class 4A championship at 3:30 p.m., while Ehret will play Zachary for the 5A crown in the final game of the LHSAA football season at 7 p.m.

If things had gone according to plan, the streak would have been taken care of last weekend during the championship games for select schools.

But Rummel, a No. 1 seed, was upset by No. 6 seed Catholic on Friday night on a last-second field goal in the Division I championship game.

In fact, the lower seeded teams won all four championship games last Friday, with No. 6 Southern Lab trouncing No. 4 St. Mary’s in Division IV, No. 3 Notre Dame beat No. 1 Riverside in Division III and No. 4 Parkview beating No. 2 St. Thomas More in Division II.

The designated home teams were 0-4 over the weekend in the Dome. Heck, the Saints, who call the Dome their home full time, are just 3-3 in the building this season.

So that’s good news for Karr and Ehret, who will both be on the visitors sideline on Saturday night.

Based strictly on the seeds, neither wa supposed to have made it this far.

Ehret entered the playoffs a No. 9 seed, and Karr was seeded even lower at No. 14.

Apparently seeds don’t take into consideration Ehret’s defense or Karr when quarterback Aldon Clark is on the field.

Ehret’s Red Brick Wall defense continues to give opposing teams fits.

No team has scored more than one touchdown against the Red Brick Wall in the past eight weeks.

How stingy is the defense.

In Ehret’s 7-6 win over Mandeville on Friday night, Skippers’ coach Guy LeCompte took his chances on kicking a Hail Mary instead of throwing one.

Mandeville had the ball at its own 48 yard-line and attempted a 69-yarder as time expired. As crazy as it sounds, Joseph Bulova’s kick came pretty close, landing deep in the end zone, but short of the crossbar.

When it finally landed, the Patriots had punched their ticked to the championship game for the first time since 1985, over a decade before any players on the team were born.

Meanwhile, Karr is returning to the Dome, which has been like a home away from home for the Cougars.

Clark, the Cougars’ prolific junior quarterback, once again led the way, throwing for 416 yards and four touchdowns in the 34-21 semifinal victory over Franklinton.

For the season, he has thrown for 3,461 yards and 34 touchdowns. As mind-boggling as those numbers are, they could be even higher if he hadn’t missed a game with an injury.

Karr will likely need one last stellar effort from Clark to knock off perennial power Neville, the undefeated and top-seed in 4A looking to repeat.

Ehret, meanwhile, will need its defense to provide one more lights out performance to end its 30-year title drought.

Ehret coach Corey Lambert would love nothing more than to win one for the folks in Marrero.

Karr coach Brice Brown, likewise, wants to do it for Algiers.

The New Orleans streak is depending on you.
