The Steelers defense has stiffened recently with the improved play of young DBs Artie Burns and Sean Davis, nose tackle Javon Hargrave and pass rusher Bud Dupree. Pittsburgh's biggest struggle this season has come with missed tackles (shines light squarely at Mike Mitchell). Ajayi led the NFL in yards after contact, and Landry and Parker are uber elusive after the catch. If the Dolphins playmakers shed tacklers in space, it could make up for the lack of field-stretching opportunities with Moore under center. A few broken tackles that lead to TDs will help Miami keep pace with their highflying counterparts.
