According to the Elias Sports Bureau, NFL defenses have been successful 74 percent of the time this season when it's third and 7 or longer, with success defined as not allowing a first down. Yet the Patriots' defense is at just 59.4 percent, a figure that accounts solely for passing plays but does factor in quarterback scrambles that are a result of good coverage or a strong rush.
The struggles continued this past Sunday against the Steelers, with quarterback Ben Roethlisberger almost making it look easy in picking up first downs on third and 7 (Nate Washington 15-yard catch), third and 12 (Washington for 16), and third and 9 (Hines Ward for 11).
Overall, opponents have converted at least one third and 7 or longer in each of the last eight games against New England.
Defensive coordinator Dean Pees keeps a scorecard to grade the defense on each down. He rates a victory on first down as holding the opponent to 3 yards or fewer, a win on second down as setting up a third-and-4 situation or longer, and a triumph on third down as stopping the offense short of a first down.
The Patriots are getting knocked out in the final category, ranking 29th out of 32 teams on third down (44.7 percent). The long-yardage passing situations have been killers.
Consider that on third and 10 or longer, defenses across the league have been successful 81.4 percent of the time. The Patriots, again accounting solely for passing plays, are at 67 percent.
The Patriots also lag on third and 15 or longer, a situation that hurt them in overtime against the Jets Nov. 13 when tight end Dustin Keller hauled in a 16-yard pass on third and 15. Defenses have been successful 91.3 percent of the time this season. New England, however, is 5 of 7 (71.4 percent).
That the Patriots have been poor on third and long reflects breakdowns in several areas, but above all else, it shows their lack of consistency in coverage and pass rushing, two cornerstones for any defense.
"Generally it's been something different every doggone time, and it's usually dealing with some kind of a technique problem," Pees said. "That's what bothered me about this last game, where we have everybody covered but a guy."
