Oklahoma and Texas players can do a lot during their careers, but ultimately, many write their legends on the field at the Cotton Bowl on a Saturday in October at the State Fair of Texas.
Adrian Peterson made his mark back in 2004 when, as a freshman, he rumbled for 225 yards in a 12-0 win against the Longhorns.
Vince Young threw three touchdown passes back in 2005 as Texas ended a five-game losing streak to the Sooners and went on to win the national title.
Oklahoma's Sam Bradford threw for three touchdowns in a win in 2007 that announced this curly-headed redshirt freshman was for real.
DeMarco Murray capped a huge career in 2010 with a pair of touchdowns and a 100-yard game, validating his status as a Sooner great.
Who will it be this year? Call it a Texas Trio.
Malcolm Brown and Joe Bergeron had a combined 51 yards and no touchdowns in last year's game. Johnathan Gray has never even suited up for a Red River Rivalry.
This week, the three of them will be too much for Oklahoma and take the next step on Texas' road back from a 5-7 season in 2010. The past two years, Oklahoma has earned victories at the Cotton Bowl, but it's Texas' turn and Brown, Bergeron and Gray will lead the way.
Brown is coming back from an ankle injury and his status is shaky, but Bergeron and Gray filled in admirably against West Virginia last week. Gray showed the best burst of any back in a long, long time with a 49-yard sprint against the Mountaineers.
He might break another one this week, and the freshman's long wait for his first career touchdown ends on Saturday. Bergeron has embraced his status as a touchdown vulture this season, leading the Big 12 with nine rushing touchdowns.
The three of them can be difficult for any defense to stop, and they'll prove that to Oklahoma on Saturday, transforming into players who have written a solid legacy in the Red River Rivalry with a performance that carries the Longhorns to a victory against their biggest rival.
