The Bears decided this offseason to go from a 4-3 defense last year to a base 3-4 defense under new head coach John Fox and defensive coordinator Vic Fangio. To do so would require linebackers who could attack the quarterback and were versatile in coverage.

The first order of business when free agency began this year was to bring in former Baltimore Ravens OLB Pernell McPhee.

Obviously being a prized free agent acquisition carries with it a high level of expectation. And through the first two weeks of the season, McPhee was able to generate a little bit of pressure on quarterbacks Aaron Rodgers and Carson Palmer — and almost had a couple sacks but let them escape his grasp — but he underperformed what was expected of him.

Sunday against the Seattle Seahawks, McPhee finally made his presence felt. McPhee was second on the team in tackles behind safety Antrel Rolle and also recorded two sacks of Seahawks quarterback Russell Wilson.

I would expect much like the entire defense, McPhee will settle into his new role as a starter and pick up his production as the season wears on.
