The Bears' revamped front seven on defense, which was supposed to be a strength this season, struggled in Sunday night's 31-17 loss to the Cowboys.
Part of the reason no doubt was that outside linebackers Pernell McPhee and Lamarr Houston, inside linebacker Danny Trevathan and nose tackle Eddie Goldman all missed the game due to injuries. But defensive coordinator Vic Fangio isn't using that as an excuse as the Bears prepare to host the Lions Sunday at Soldier Field.
