"Bernard had some good snaps in the game and then he had some bad snaps," said head coach Dick Jauron. "That's really true of everybody in any football game but we felt like a change was necessary and Marc did OK."
However, Robertson was named the starter for the critical match-up with Green Bay. He faces his most difficult test against the Packers. Robertson will go up against Joe Johnson and Kabeer Gbaja-Biamila, who totaled 22.5 sacks between them in 2001. Another poor performance could mean the Bears would start Colombo following the bye week at Detroit.
"Everybody knows that in the NFL if you're not getting the job done, you move on to the next guy and it's the same at every single position," Shoop said. "He's (Robertson) going to step up and we're counting on him getting the job done this week. We're not planning on making any changes, we're planning on him blocking whoever they put in front of him."
The team has a recent history of not always starting the best player. Brian Urlacher didn't start the first two games of his rookie season because he was at strongside linebacker instead of patrolling the middle. Last year Anthony Thomas didn't earn a start until he rushed for a franchise rookie record 188 yards against the Bengals in the team's fifth game.
Colombo could be the solution the Bears have been searching for, but the problem is how long will it take to find out.
