Jets Underground isn't a history of the New York Jets. It's the true story of the New York Jets. From the insane to the unbelievable, Jets Underground is a collection of the maddest and baddest of everything that truly makes the Jets the Jets. The Jets may not be a model franchise. They may not have won multiple championships. They may not be America's team, or even of New York's team. But to the loyal, diehard fans of Jets Nation who live and die with every play, they're the only team.
