Typically, Notre Dame coach Marcus Freeman tells his players on defense that he wants them to play loose and free and not get too caught up in technical details. Freeman senses an exception to the rule, however, as No. 12 Notre Dame (6-1) prepares to kick off against No. 24 Navy (6-0) on Saturday afternoon at MetLife Stadium in East Rutherford, N.J. Technical details are vital to stopping Navy's triple-option offense, Freeman said, so playing "fit ball" could take priority over playing "football" for once. The undefeated Midshipmen, who are coming off a 51-17 victory over Charlotte last Saturday, are averaging 44.
