For the Bears Cover 2 to be successful, Rod Marinelli's Rush Men need to apply pressure on the quarterback and force him into making bad decisions. The system requires the defensive line to be quick at the snap and be disruptive in the gaps.
Over the past couple seasons, Jerry Angelo has made improving the defensive line a priority. While Angelo signed Julius Peppers to a six year, $91.5 million contract, as an edge rusher, the defensive line's performance relies on how disruptive the three technique tackle can be.
Henry Melton and Amobi Okoye are the three technique tackles who need to be productive to give the Bears defense it's best chance at success. They are what Tommie Harris was with the Bears in 2005-2006. With Jay Cutler's return to the team in question, the defense will be heavily relied on to help shoulder the burden.
According to ProFootballFocus.com, Melton (16th) and Okoye (14th) are ranked as two of the most productive interior defensive linemen.
In 323 pass rushes, Melton has 25 total pressures, 7.74% per pass rush. Okoye, in 256 pass rushes, has 21 pressures, 8.2% per pass rush. Both have combined for 9 sacks, Melton (5) and Okoye (4).
Peppers, the NFC Defensive Player of the Month for November, on the other hand, did not rank in the top 25 of pass rushers. Peppers' value cannot be measured through the stat sheet because he commands a double team or a chip on almost every snap and forces holding and false start penalties not to mention the number of passes he tips or defends. Because of the extra attention he's given, he allows more opportunities for others to make plays and progress.
