As you can see, Jamison Crowder was the primary punt returner last season, though DHall acted as the returner two times. Hall is sort-of-almost retired now, and a lot of concern lingers from the many muffs and fumbles that plagued Jamison Crowder in 2017. I think everyone wants to have options at punt returner to prevent a replay of last year.
In 2017, kick return duties were primarily handled by Baushaud Breeland and Chris Thompson, but seven other players returned one or more kickoffs during the season.
With Breeland no longer a Redskin, and Chris Thompson returning from injury, there is reason to think that the coaching staff might want to identify a new man to handle kickoff returns.
