The sprint to reach Lions quarterback Ty Detmer and recording a shutout became amusement for the Bears defense to pass the time until the final gun during the second half.
They came up with six sacks -- defensive linemen Bryan Robinson, Phillip Daniels and Alfonso Boone made one each, defensive back Jerry Azumah blitzed for two and blitzing from Colvin gave him one and lifted his total to a team-leading 10 He also forced a fumble.
Colvin became the first Bears player with double figures in sacks since Jim Flanigan in 1995.
``We were just out there having fun,'' Colvin said. ``You saw what happened.''
Detmer flattened across the Silverdome turf or hurried into throwing interceptions to Walt Harris and Warrick Holdman ensued.
Colvin was having success coming off the edge and hurring Detmer. Before getting shaken up during mop-up time, Daniels had made tackle rookie left tackle Jeff Backus' life miserable with a sack in addition to forcing drive-killing holding and hands-to-the-face penalties.
Colvin said he sized up Backus and Lions right tackle Matt Joyce in the Bears' 13-10 win and felt with better footing on artificial turf, he would have no problem.
``After the first game I felt confident in my ability to get around the corner,'' he said. ``Everyone was stepping up and making one-on-one plays when they have to.''
The Bears' six sacks were their most since Week 3 against Atlanta when they had seven. For the season, they have 44 sacks, or eight more than last year and nine more than Baltimore's Super Bowl champion defense had last season.
``It wasn't just me,'' Colvin said. ``There was a lot of guys getting back there and getting pressure on the quarterback. We've been criticized a lot for not getting to the quarterback, not creating pressure.
``But it's all in the defense, all in the scheme You've just got to create opportunities.''
They credited the offense for providing those opportunities by providing a lead, but they did a fair job in their own right.
Good field position helped the Lions reach their own 49-yard line or beyond on all six first-half possessions. Detroit had nothing but a 17-0 halftime deficit to show for it.
The Lions never got past the Bears' 20 in the game, their leading rusher was Lamont Warren with 19 yards on six carries, one better than Detmer achieved on scrambles, and they were held to 15 percent third down conversions (2-of-13). In the closing minutes, preserving the shutout became as big a goal as tossing around Detmer.
``For our defense to get a shutout, that's hard to do now in the National Football League,'' coach Dick Jauron said of the Bears' second shutout this season.
In the final minutes, the Bears' defense played with a fervor of a team involved in a tight game.
``We knew the game was in hand at the start of the fourth quarter,'' safety Mike Brown said. ``In the latter stages of the game, that becomes the game -- the game in a game.
``You could tell they wanted to score really bad and we didn't want them to score.''
It was just one other thing the Lions offense was unable to accomplish on a day of Bears defensive dominance.
