Carroll's advanced coverage numbers in 2013 were indeed rather impressive, and he has been incredibly consistent throughout the past three seasons. In 451 coverage snaps, the fourth year corner allowed just 43 receptions, or 10.5 coverage snaps per reception. To provide some context to that,
Chris Harris allowed a reception every 11.6 coverage snaps, while DRC was third in the entire league, allowing a reception every 15.7 coverage snaps (advanced stats courtesy of
Pro Football Focus).
Opposing quarterbacks did not fare well when throwing at Carroll, with just a 65.0 quarterback rating when targeting receivers who were covered by the Dolphins corner. This number is identical to the rating that opposing QBs had when
throwing at Chris Harris; DRC registered a 67.8 QBR against in 2013.
