Good teams manage to find ways to persevere in spite of self-inflicted wounds. Such was the case of the Jacksonville Jaguars when they beat the Arizona Cardinals in Week 12. Although they had their NFC West against the ropes at several points, they were unable to put them away in regulation. The game ended up going to overtime, where both the offense and the defense delivered to win 27-24.
You could make the case that Jacksonville barely survived. A team such as the Cardinals shouldn't have given it so much trouble, but that's how things played out on any given Sunday.
