The day has come. The famous Red River Rivalry showdown in Dallas, Texas, is here, and the stakes are through the roof. 

Texas is looking to keep its season alive after a rough 3-2 start, and No. 6 Oklahoma is seeking to improve to 6-0 on the season, and keeping its perfect season intact. The Longhorns have their work cut out for them, especially with Sooners junior quarterback John Mateer expected to return.

Here are three things Texas must do if it wants to leave the State Fair of Texas wearing the golden hat.

Quick Game

After the Longhorns' 29-21 loss to Florida, the main storyline was their offensive line's struggles. If the Gators gave them that much trouble, Oklahoma's defensive line ranking tied for second in sacks can cause havoc in Texas' backfield. 

It may be too big an ask for the Longhorns to fully contain the Sooners' pass rush, but what they can do is get the ball out quickly. Texas head coach Steve Sarkisian is highly regarded for his creative screen plays and for utilizing his speed out of the backfield. That will be required on Saturday.

Texas redshirt sophomore QB Arch Manning has struggled with short passes this season, and that has to improve if this game plan is going to work.

Rattle Mateer

Oklahoma's starting QB is pushing physical limits to be available for this game. Mateer will not be 100%, and that's something the Longhorns have to take advantage of. 

Texas defensive coordinator Pete Kwiatkowski needs to send a message early with blitzes, early and often. This is a must-win game, and as many in sports say, the coaching staff needs to empty the clip.

It's also vital that Longhorns sophomore edge rusher Colin Simmons builds off his best game of the season. Simmons didn't record a sack against Florida, but he did have a tackle for loss and other plays that don't show up in the box score. The pass-rush starts with Simmons, and they need to pressure Mateer at all costs.

Texcalibur

The easiest way to pull off an upset is to take the ball away from your opponent. That's especially true in this game, where teams are always one play away from flipping the game upside down.

So far this season, Texas has had a slight drop in takeaways per game, ranking tied for 26th in the nation. Not elite, but not bad. However, it ranks tied for 61st in college football in turnovers per game, with 1.2. The good news for Longhorn fans? Oklahoma doesn't force a lot of turnovers, ranking tied for 116th in the FBS.

The task is simple: if Texcalibur is busy, and Texas wins the turnover battle, its chances to win this contest skyrocket.
