In a recent interview with NPR, Connie Britton (who plays Tami Taylor on Friday Night Lights) said that both she and Kyle Chandler (who plays Coach Taylor) "agreed that we did not want this to be a marriage where we ultimately were addressing infidelity or whatever" because "we really wanted to deal with the authenticity of what it is to try to make a marriage work." Britton added that "if you're in what we'd consider to be a good marriage, there's going to be a foundation there. There's going to be a foundation that is solid. So on top of that foundation, you can rock the boat every which way that you want to, and be able to go back to what's at the core of it."
As many commentators and bloggers have noted, the Taylors' union is one of the best real depictions of a good marriage perhaps in the history of television. There are no sensationalistic storylines involving infidelity, illegitimate children, mistrust, or even just spite. The Taylors truly are a team. They respect each other, and it's the security that they exude and the trust in each other that they display that make this marriage different from most that are depicted on television.
So when Glen—a counselor West Dillon High who has had a major crush on Tami, planted a drunken, unwanted kiss on a very unsuspecting Mrs. Taylor two episodes ago—blindsides a similarly unsuspecting Coach Taylor (Tami kept the kiss a secret) with an admission of his indiscretion, the security of the Taylor's marriage shines through.
