Keith Butler devised a new defensive alignment Sunday against the Dallas Cowboys, using five linebackers and no cornerbacks.
The Steelers defensive coordinator might need to come up with something else now that end Cam Heyward is out for the rest of the season with a torn pectoral muscle.
Heyward is one of the best, if not the best defensive players the Steelers had, and the replacements were not nearly up to his standard when he missed two games at Miami and to New England.
As it is, the Steelers rank 25th in the NFL in average yards allowed per game, 380.
