Undrafted out of Kansas last spring, Sims fought his way to a spot on Washington's 53-man roster, opening the season with a role on kick returns and a handful of snaps per game on offense. He scored a 65-yard touchdown on an end-around Week 5 and a 91-yard TD on a kick return Week 12, setting the stage for increased playing time once slot specialist Trey Quinn suffered a season-ending concussion in early December. Sims quickly proved to be an upgrade on Quinn, catching 20 of 36 targets for 230 yards and four TDs over the final four weeks of the season. The strong finish should make Sims the favorite for slot work in 2020, but that doesn't mean he won't have any competition - potentially from both Quinn and third-round pick Antonio Gibson. The team claims it wants to use Gibson out of the backfield, but his skill set could also translate to wide receiver, which happens to be a less crowded position in Washington. Of course, Sims can make it a moot point if he picks up where he left off in December.
