If the players who take major steps back in 2015 return to form (Rodgers, Lacy, Adams, etc).
Last season seemed like a regression, probably due to an almost SB hangover plus the coaching staff shakeups.
Yes, we dropped the 3 games at home to the division rivals, but we also won in their houses as well. And those teams could barely put the Packers away despite the Packers playing some of their worst football in years. The Panthers are likely to take a step back, as are the Cardinals (young weapons, old QB, shaky line, NFC West likely improving). The Vikings are likely the biggest challenger for the division, but they'll be putting a lot of their chips in on a 31 year old RB who wasn't quite the AP everyone remembered.
