Correct, we need to improve on that. However, as has been stated in numerous other posts, there is very little correlation between 3 and outs and TEAM success. The Patriots, Giants, Dolphins, Broncos are all worse than us in that regard (yes, the Patriots rank below us); and we're within 1% point of Oakland, Titans, and Lions.
4 of the Top 5 teams in the category didn't make the playoffs: Redskins, Saints, Panthers, Chargers.
