On the practice grounds of a park in Bethany, a different type of Red River Rivalry is revving up.
"We're finding those roles, who still has some athleticism and who's going to be doing the less athletic things. I can't have Austin with all the bragging rights," said Norman resident Tim Wilson.
When Tim says Austin, he doesn't mean the city.
That would be Austin Chittim, from Austin.
"My dad kept it easy. You're from Austin, your name's' Austin, your favorite color is burnt orange," said Chittim.
While Austin and Tim are on opposite sides of the rivalry, they're coming together for a very special cause after connecting on Twitter.
"I just made a comment on Twitter about being 6'5" and left-handed. He kind of messaged me on Twitter and was like, 'Do you want to be the quarterback of the OU team?' and I was like, 'Not really.' But here we are, we're doing it now," said Chittim.
Austin is quarterbacking a charity flag football game in Dallas, October 8 on Red River weekend, with the proceeds going towards some worthy causes.
There's Gridiron Heroes, a Texas-based foundation that helps high school football players like Cory Fulbright, who suffered a catastrophic spinal cord injury.
Then there's Tycen Edwards, an OU super fan who is battling cancer.
"Those two foundations really called home for me, and it was just something I said, 'Let's have fun, let's be competitive, let's face each other in a fun atmosphere and let's also raise some money for some good causes,'" said Chittim.
While both sides do not want to lose in this rivalry, the final score won't decide the true winners that day.
"We're very passionate about this game, and it's just neat that we can have that love/hate, because where are you without your rival?"
