It's the same something that's affected the past 10 NFC Super Bowl representatives -- injuries (Rams in '02, Eagles in '05), league-wide parity (Panthers in '04), team distractions (Buccaneers in '03), retirements (Cardinals in '09, Giants in '08), mediocre defense (Seahawks in '06), Marshawn Lynch (Saints in '10), no offense (Bears in '07).
Along with that, the NFC's streak of a different team representing the conference in the Super Bowl for 10 straight years is pretty impressive. So will we have a new franchise representing the NFC come February? There are six candidates -- the Cowboys, Falcons, Lions, 49ers, Redskins and Vikings -- and I consider only two to have a shot.
First, the arguments for Atlanta
» Atlanta was 13-3 in a very competitive NFC South last season, and secured the No. 1 seed in the playoffs.
» This a well-coached team, as evidenced by the fact that the Falcons ranked first in penalties called against, kick returns, long scoring drives, total rushes and completions. Oh, and their opponents had the worst field position in the league.
» They've got the best set of triplets in the NFC with quarterback (Matt Ryan), running back (Michael Turner), and wide receiver (Roddy White).
On the flipside
» It's nearly impossible to repeat as the top seed anymore. Therefore, this team must win on the road in the playoffs. Considering they were Clubber Lang'd by the Packers at home in the postseason, that's a tall order. And that's if Mike Smith can get his club back there.
» Smith is starting a rookie wideout opposite White, has a new left guard, and age is creeping in at some key spots on the roster, namely Turner, tight end Tony Gonzalez, and pass rusher John Abraham.
Outside of Atlanta, the other team with an outside shot to keep the NFC streak alive is Dallas, but many a bump would have to be smoothed over.
Biggest obstacles for 'Boys to make a trip to Indy
» Let's start with offensive line, where the injured Montrae Holland, Phil Costa, or somebody mediocre is penciled in at guard while rookie Tyron Smith is slated at right tackle. Trying to win the NFC East with a makeshift line is a tall order, irrespective of the fact that the Eagles are more loaded than an Alec Baldwin voicemail.
» The second major issue for Dallas is the secondary, where the backup corners were destroyed last week against the Chargers and the safeties have been a weakness since Darren Woodson hung 'em up seven years ago. The Cowboys gave up 57 pass plays of 20-plus yards a year ago (tied for 28th in the NFL), and with Rob Ryan's penchant for sending the house (like he tried early against the Chargers), the back four's deficiencies could be further exploited by the likes of Aaron Rodgers, Michael Vick, and Drew Brees in the NFC race.
