Were you open downfield against the Patriots on Sunday? Chances are that you weren't, but most able-bodied men in the Pittsburgh area on Sunday probably could have run a 15-yard dig against New England and picked up their first NFL catch without really being bothered. In a game that felt nowhere near as close as the final score, the Steelers simply bludgeoned a dismal Patriots pass defense with pass after pass. In fact, Ben Roethlisberger very clearly left some points on the table by missing open receivers. The Patriots looked like they very well might have the worst pass defense in football this weekend. And nobody should be surprised.The Patriots have been preparing for this day for several years now. They just have very little to show for their preparation. Over the past five seasons, the Patriots have used 11 picks in the first three rounds of the NFL draft on defensive players. Only three of those players started on Sunday, and only one — safety Patrick Chung — has been playing at an above-average level this season. Three more (linebacker Jerod Mayo, cornerback Ras-I Dowling, and defensive lineman Ron Brace) are injured. Linebacker Jermaine Cunningham, a second-round pick in 2010, was a healthy scratch. The other four players have all been cut, including three players who would have been important cogs in the New England secondary if they'd developed. If Matt Millen had made these same 11 picks, we'd be laughing at him.Instead, New England is left starting a group of underathletic journeymen and past-their-prime spare parts, a defense full of misfit toys. Their 11 starters on Sunday included a pair of undrafted free agents (Kyle Love and Gary Guyton), two players signed off of other teams' practice squads (Rob Ninkovich and Kyle Arrington), two Jets castoffs (Shaun Ellis and James Ihedigbo), and 32-year-old pass rusher Andre Carter, who lost his job as a member of that legendary Redskins front seven last season. Unwanted veteran free agents like Antwaun Molden and Mark Anderson see significant snaps as reserves, and if Albert Haynesworth ever stayed healthy, so would he. The Patriots offense has Tom Brady to serve as the centerpiece that makes everyone else look and play better. On the defense, Vince Wilfork is a very talented lineman, but there's no way he can have the impact on the rest of his teammates that a Hall of Fame quarterback can. It's just not realistic.Carter serves as the primary member of the Patriots' pass rush, which has fluctuated from disappointing to nonexistent over the past few seasons. After Mike Vrabel picked up 12.5 sacks in 2007, the Patriots simply haven't gotten consistent pressure from one player or one position. The last player drafted and developed by the Patriots to put up a season with more than five sacks was Tully Banta-Cain, taken in the seventh round of the 2003 draft. Cunningham was supposed to offer some ability as a pass rusher, but he now has one sack through his first 16 games. Before sacking Roethlisberger five times in 55 dropbacks on Sunday, New England was 30th in the league in sack rate.1 And those five sacks were almost exclusively of the coverage variety, as Roethlisberger — who has been sacked more frequently than any active starting quarterback besides Michael Vick — spent extra seconds in the pocket waiting for the perfect throw.The Patriots were able to patch over their problems last season with the balm we discussed in our team preview — turnovers. They had an unsustainably high turnover ratio and takeaway percentage last year, and both those figures have declined in 2011. The only thing that's really kept them afloat in 2011 has been the long fields provided to them by the New England offense; even when Tom Brady turns the ball over, it's usually been deep inside opposition territory. The 73 possessions the Patriots have faced have started with an average of 76 yards to go for a touchdown, the deepest starting field position in football. Even as the Patriots offense struggled on Sunday, Pittsburgh didn't start a single drive from outside their own 33-yard line until there was 2:35 left in the game. Against a team that was allowing a league-leading 39.4 yards per drive heading into the game, the Steelers produced 28 first downs. During the first three quarters of the game, Pittsburgh had seven possessions and went three-and-out just once. Their other six drives each went for 52 yards or more, and only the two-minute drill failed to run at least five and a half minutes off the clock. Those drives only produced 23 points because the Steelers struggled to cash in once they got to the red zone. This game very easily could have been a 37- or 40-point performance from the Steelers. That's how bad the Patriots were on defense.The real problem for the Pats is that this isn't likely to get better. Mayo will get healthy, but after the Patriots placed Dowling on IR and released Leigh Bodden this week, there's no great cornerback about to suddenly appear in their secondary.2 Teams like the Jets and Cowboys were strangely hesitant to get in a shootout with the Patriots, but any team with even a decent passing game is going to want to fling the ball around 40 times and force the New England secondary to make plays. Considering that the Patriots will likely have to make it through either the Bills, Chargers, or Steelers in the AFC playoffs, it's hard to imagine them getting very far without a sudden, unexpected improvement in the play of their pass defense. Again.
