Tyra - Underdogs Tyra Collette is a seemingly popular girl with a rebellious streak, and there's never a dull moment when she graces the screen. She is Tim Riggins' on-again, off-again girlfriend and seems to be one of the only people in the town who doesn't follow football religiously, and is often disdainful of the way the Dillon Panthers are worshipped. She appears to have a passionate dislike towards Lyla Garrity and is furious when she discovers Lyla and Tim's affair. However, her relationship with Lyla later progresses into a sort-of friendly one in later seasons.
