For a guy who has spent most of his career as a backup, Texas' Case McCoy carries himself with the swagger of a national championship-winning quarterback.

Whether it's leading Texas to an upset win over rival Oklahoma, or surrounded by reporters during game-week interviews, McCoy eases his way through just about every situation.

It's that swashbuckler's attitude has allowed McCoy to step in for injured David Ash and lead the Longhorns to three consecutive victories. Texas (4-2, 3-0) plays at TCU (3-4, 1-3) on Saturday.

The win over Oklahoma was arguably the brightest moment for a player who has struggled tried to live up to legacy of older brother Colt, the Longhorns' quarterback from 2006-2009 who led Texas the 2009 Big 12 title and the national championship game.
