It takes more than a couple sturdy runners to win the NFL championship. A good defense, a solid offensive line, good coaching, and those pesky "intangibles" (like having the resolve to overcome a defecit, keeping composure by limiting the amount of stupid penalties and turnovers, and not getting too complacent when your team is ahead) also go a long way towards winning a title. Having more than one guy is great, but if that's all it took, Atlanta would've won a couple Super Bowls by now.
