This is a crowded field, but for me, I'd say Dallas. At the time, Dallas looked like a strong playoff contender and Tony Romo still looked like a franchise QB coming off a big game the week before beating the champs in their house convincingly. Seattle won this game by 20 points and looked utterly dominant in doing so. It is still the only decisive win or loss of the entire season. And if you hate Tony Romo this game has bonus points, as it appeared that this game might have been the beginning of the end for his career. He's having a career worst season after posting 300+ yards and 3 TDs right before facing our defense.
All four of our losses have been tough, but the Rams hurt the most for me. Unlike the other three losses, Seattle looked like the better team, but lost basically because of one special trick play and a timeout the refs didn't see. It was also a game that had an inexplicable number of 3rd and long conversions. Giving up 3rd and long to a white hot Matt Stafford or Tom Brady is one thing, having it happen against Sam Bradford is another. Oh yeah, the Rams also went 2-2 on FGs from 59+. And we lost by 6 points. Yeah. We win that game, and you wouldn't have to be delusional to still think we have a great shot at the division this year.
How about you guys?
