Wondering if someone can answer this question for me.  How are the play-off organized?  I ask because I occasionally pop over to check out "The Absurdly Premature Playoff Picture" blog post at Yahoo Sports (http://sports.yahoo.com/nfl/blog/shutdown_corner/post/The-absurdly-premature-playoff-picture-Week-10?urn=nfl,203407) and a few weeks back they had the Packers making the Playoffs but they were on the other side of the NFC playoff bracket branches (so to speak) - after this past week's win, they've been moved to a position where we'd have to play them BEFORE getting to the NFC Championship game (assuming that we hold true to form here and win the Division as it looks like we might). 

What determines the exact positioning of wild-card teams in the brackets?
