I'd say the Packers have solved their issues related to guys getting open/separating downfield through a combination of quick-release passing game plus Jordy getting his legs back, Cook getting healthy and becoming a productive third-down weapon/threat, and Montgomery's emergence as a legitimate dual threat out of the backfield. Now if Adams can stop dropping TD passes look out. Ball security has been consistently good but that'll need to continue obviously.
I think the Packers key to winning in the playoffs this year is avoiding giving up big plays defensively.
Some defensive performance comparisons among NFC playoff teams/contenders...

Interestingly (to me anyway), the Packers lead all NFC playoff teams/contenders in INT's (16), Takeaways(24) and Sacks (38).
They're tied with DET as the worst defense in yards allowed/play at 5.9.
GB is the league's worst pass defense allowing 8.0 yards/attempt.
They trail SEA, NYG, and DAL in Rushing Yds Allowed/Attempt and are better than the Lions, Falcons and Skins.
They best only the Falcons in Points Allowed.
Only DET allows a higher QB Rating (they're a league-worst 105.0 Rating allowed).
NYG have an NFC best 75.8 QB Rating allowed.
