Like Aros said above, we've just got to keep stacking wins. If there's one thing we all should have learned about the NFL this season is how unpredictable it's been week to week, game to game. Falcons knock off the Bills last night. No biggie. Most pundits SB representative for the AFC this year was the now 1-5 Ravens. Last year's 4-13 Patriots are now in first place in their division. The SB champion Eagles have lost two in a row and are presently degenerating into a soap opera of dysfunction. The Seahawks a mere afterthought going into the season are now getting mentioned as the best in their division and a contending team all of a sudden by certain pundits.
At present, I don't think it's crazy to think that any one of seven teams or so could represent the NFC in the SB. It might boil down to who gets hot at the right time and remains comparatively/relatively injury free when it counts. The only thing I feel fairly confident about is that the Chiefs are going to once again be the team other teams are going to have to go through to get the Lombardi. And that's if they remain relatively stable on the injury front.
It's not completely crazy to think that we're contenders in the NFC, something that I wouldn't even allow myself to think of as being a possibility when the season began. Just keep improving, keep winning, possibly make a key acquisition, and get ready for those showdowns against the Rams forthcoming.
