Thirteen high school football state titles will be decided in California this weekend, highlighted by Saturday's 8 p.m. CIF Open Division Bowl Championship at Sacramento State University, featuring MaxPreps national No. 1 Mater Dei (Santa Ana) and No. 15 De La Salle (Concord).

MaxPreps' Mitch Stephens reports the teams have a high-profile common opponent in No. 14 Bishop Gorman (Las Vegas), which beat De La Salle 34-7 two weeks after Mater Dei broke its 55-game winning steak, 35-21. 

Bishop Gorman coach Kenny Sanchez doesn't expect a Mater Dei blowout.

"I think it's a good matchup for De La Salle," he said. "They have the kind of offense that can chew up time with long drives and keep Mater Dei's offense off the field. They just have to make sure they finish."

While averaging 50.5 points per game, Mater Dei (14-0) has beaten its impressive list of postseason foes by an average of 34 points per outing, including last week's 49-24 win over then-No. 3 and defending state champ St. John Bosco. Quarterback and USC commit JT Daniels received a significant honor this week:

De La Salle (11-1) hasn't played a game closer than 17 points since that Bishop Gorman loss on Sept. 16. The Spartans still come in as a big underdog, with four current Division I recruits compared to Mater Dei's 19. One of those, running back Kairee Robinson, will draw a lot of defensive attention on Saturday.

Oklahoma team makes post-title pit stop 

When you reach your ultimate goal, you have to celebrate right, and the Afton Eagles did just that after capping a perfect season with a 44-12 Class A championship victory over Crescent. 

Mike Brown of the Tulsa World says that via recommendation from senior guard Tatum Maupin, the team duplicated the routine from its semifinal victory the previous week, when it stopped at Whataburger post-game.

"He thought we needed to do the same thing," Afton coach Zach Gardner said. "He’s our food (expert), and he ranks the restaurants as we drive by them on a road trip. We try to give him a say when we can."

Maupin and fellow linemen Seth Miller, Jacob Barton, Travis Lukens and Braeden Gaines earned their choice by clearing the way for quarterback Wil Amos, who had 39 carries for 418 yards and six touchdowns, to become the fifth player to rush for 400 yards in an Oklahoma playoff game.

As fans gathered for a celebration back at the school, they just had to wait a tad bit longer.

Coaches warn of social media mistakes

Richard Obert and Jeff Matcalfe of the Arizona Republic spoke to coaches this week about recruits' social media use, after this tweet surfaced from Ottawa University-Arizona coach David Moseley:

Just dropped another recruit for profanity and acting like a fool on social media. If you can’t be trusted on twitter how can you be trusted with our logo on your chest? #CharacterCounts

— Coach David Moseley (@CoachMoseOUAZ) December 13, 2017

McClintock (Tempe) High School coach Corbin Smith said, "Kids don’t understand that social media should be used to promote themselves in a positive light and show what their lives are about. Instead, it is being used by young people as a popularity contest, ego and just to gain attention ... Unfortunately, this is the world we live in, and young people rarely look past their nose to understand the future ramifications of their use of social media."

Mariota says he's sorry to reporters

No one is above getting scolded by their mother, as Tennessee Titans quarterback Marcus Mariota recognized after last week's 12-7 loss to the Arizona Cardinals. Mariota's mom didn't like his tone during the post-game presser, and told him so, which led to this:

Known for setting a good example in many ways, Mariota came through once again.
