And then even harder.
One week after holding the defending NFC champs to just nine points, Detroit was drubbed in every facet of the contest, falling 34-7 in a penalty-plagued game in which the phrase 'shot themselves in the foot' was redefined.
Detroit fumbled away their first two possessions and committed 10 first half penalties en route to a 24-0 first half deficit. But the most crueling blow took place in the second half.
After quarterback Jon Kitna fell over the goal-line for Detroit's first touchdown early in the third quarter, Chicago quarterback Rex Grossman was intercepted on the next series by Lions' middle linebacker Boss Bailey, who promtly returned the pick for a touchdown.
With the scoreboard at 24-13, and a momentum shift evident, the play was called back when Lions' cornerback Jamar Fletcher -- on the opposite side of the field -- was flagged for illegal hands to the face.
Kitna, who finished a respectable 23-for-30 for 230 yards, was harrassed throughout the contest by a relentless Chicago defense. Kitna was sacked six times, hurried many more and was victimized by costly penalties that prevented the offense from establishing any consistency.
The Lions also struggled on the ground, as running back Kevin Jones carried the ball just 12 times for 44 yards -- 29 of which came on one carry early in the game.
But while the Lions' offensive struggles carried over from last week's loss to Seattle, the Detroit defense was never a factor against Chicago and Grossman.
Grossman torched the Lions secondary for 289 yards and a career-best four touchdowns, completing 20 of his 27 attempts. Grossman was rarely pressured, never sacked, and led the Bears to a 50 percent third-down completion percentage.
Grossman threw touchdown passes of three, 41, 31 and five yards.
The Bears improved to 2-0 overall and in the division, while the Lions dropped to 0-2 with an 0-1 division mark.
