Dak Prescott's sporadic offense is as good a reason as any why Dallas has lost consecutive games for the first time in two years. Finding consistency for one of the NFL's most productive units will be a priority in the final two regular-season games for the playoff-bound Cowboys (10-5), starting Saturday night at home against NFC North champion Detroit (11-4). The offense was really good on the first two drives in a 22-20 loss at Miami, but didn't come out of a midgame funk until the Dolphins had a two-score lead (16-7) midway through the third quarter.
