But the rookie defensive coordinator is optimistic his unit can improve as the Dolphins (0-1) prepare for their home opener against the Buffalo Bills (1-0) on Sunday.

And the Dolphins must work quickly to correct their issues against the run, with Bills quarterback Josh Allen’s size and prowess as a runner coming to Hard Rock Stadium this week.
