Last season, the offensive line allowed 52 sacks. The deficiencies were highlighted by Giants' nine sacks in the middle of the season and in the NFC Championship game against the Packers. We knew the front office had to upgrade the offensive line to protect their long-term investment in Jay Cutler.
The Bears drafted right tackle Gabe Carimi in the first round. In addition, they signed former Seahawks first rounder, center Chris Spencer. While the Carimi pick was deemed as necessary, Spencer seemed to be wasted roster space.
First, Roberto Garza was already penciled to be the successor to Olin Kreutz at center. Then, Garza was named a team captain. People questioned the Spencer signing because he wasn't offered the starting job at center.
To start the season, the Bears started Lance Louis at right guard and Carimi at right tackle. Spencer was buried in the depth chart. When the two were injured, Spencer stepped in at right guard with Louis being inserted at right tackle after the Bears tried the Frank Omiyale expereiment again and failed.
Since being paired together, Louis and Spencer have mauled oppposing defenders and opened running lanes for Matt Forte. In addition, the entire unit has protected Cutler. In the first three games, the Bears allowed 18 sacks. In the last three games, the unit has allowed only three sacks.
With Carimi returning to health, the Bears should keep the offensive line as is. There's no need for him to return to the starting line up.
