You may have recently seen me mention that the Pittsburgh Steelers, while he has been out of his primary duty as a full-time defensive starter, have stuck cornerback Artie Burns back on kick coverage duty, at least on a temporary basis.
Burns has not seen work on kick coverage since his rookie season, though he did continue to be used in that role even after he entered the starting lineup full-time in the second half of the season. To have taken him out at that point would have been a disruption of the cohesion of the unit, which could lead to big plays.
