Are you sure? 10 wins should put them in automatically as a wild card given the weak NFC East. Even if it doesn't, these teams in the NFC control their destiny:
If any of those teams wins out, then they don't have to rely on any other team. Again, it is an over used term.
If Atlanta wins out they would still need every single team in front of them to lose at least one game or more.
They would need San Fran or NO to lose at least 4 more games.
Carolina, Chicago, or GB, to lose at least 3 more games.
Arizona, Philly, or Washington to lose at least one more game.
If any one of those teams loses one less game than that, ATL is out, and this isn't even taking into account any possible tiebreakers that ATL might stand to lose.
Whereas, If the Panthers win out, they are division Champs, regardless of what any other team does, hence the term "controlling your own destiny".
The term may be over used, but it's relevant here.
