In a rare move, Harbaugh questioned Martindale’s play calling after the loss in Pittsburgh on Dec. 5. That was the first of the Ravens’ six consecutive defeats to end the season. According to sources in the organization, Harbaugh and Martindale, veteran coaches with strong personalities, butted heads at times, creating occasional tension but nothing the two men didn’t work through. Sources also said that Martindale’s colorful and direct comments in news conferences rankled some high-ranking team officials.
Still, according to several Ravens staff members, there were no obvious indications that Harbaugh was preparing to make a major shakeup.
