The Redskins may not have a true No. 1 wide receiver, but they do have three guys who are absolutely making the team at that spot for 2018: Josh Doctson, Paul Richardson and Jamison Crowder.

What happens after that, though, is about as defined as Tom Brady's upper body. In other words, it's not exactly defined.

So, let's compare Trey Quinn, Maurice Harris, Brian Quick and Robert Davis (there are other guys competing at wideout as well, but these four are the most established and the most likely to be in the discussion for the final 53). What is one quality each guy can claim is unique to him as they look to stick around and what's the biggest question they each must answer in order to do so?

Here's a breakdown.

Trey Quinn

His unique quality: Being a 2018 draft pick

Quick was a free agent signing last season, while Harris was once picked up as an undrafted free agent and Davis was drafted last season. Additionally, Harris and Davis have both already been cut by Washington in the past.

Quinn, on the other hand, is the newest of the bunch and teams can be hesitant to cut ties with draft selections just a few months after taking them, even when those selections are merely seventh-rounders. Being the newest and youngest of these targets could really benefit him.

His biggest question: Can he help on special teams?

Harris has returned a couple of kicks as a pro and he almost had to help out on punts in 2017. Quick and Davis, meanwhile, are stronger athletes who can help tackle on coverage units. But what does Quinn do on specials?

At SMU, he took back just six punts, so those thinking he's an automatic fit to do so in the league aren't exactly right. Whether his first NFL job totally relies on contributions to the third facet of the game isn't clear as of yet, but it'd certainly help his case.

Maurice Harris

His unique quality: Versatility

Harris sure doesn't look like a slot wideout, but he's lined up there some in 2018 camp and, if necessary, could be thrown into it on a gameday. The other three guys are much more locked into their spot on the offense — Quinn in the slot and Davis and Quick on the outside.

Of course, Quinn is an obvious fit as a backup to Jamison Crowder on the inside. But if Harris shows a good enough grasp of it in the preseason, perhaps Jay Gruden will go with him as a Ryan Grant-esque option who can line up all over.

His biggest question: Can he get open enough vs. opposing defenses?

Harris' 2017 catch vs. the Vikings will live on forever, but he only has 11 other career grabs. He routinely pops open in Richmond and rarely lets a ball hit the ground if he gets his hands on it, but it's time for him to be more of a threat in real action.

Brian Quick

His unique quality: Experience

Davis and Quinn have yet to record an NFL reception and Harris has just 12. Has Quick been a standout since being drafted in the second round in 2012? No. But he's the owner of 111 career catches as a pro and is a 29-year-old veteran.

Last season, Quick proved he could come off the bench at a moment's notice and produce with that highlight vs. the Seahawks in Seattle. That is a valuable skill to have.

His biggest question: Is his ceiling too limited?

You can use Quick's 111 catches since 2012 as an argument for keeping him. You can also use it as an argument for getting rid of him.

At this stage of things, it's unlikely Quick takes a massive step forward or suddenly becomes a major part of an offense. Therefore, Washington may opt to drop him on cutdown day in favor of his competitors who have chances to grow into a player who's more capable than Quick.

Robert Davis

His unique quality: Athleticism

At the combine before the 2017 draft, Davis ran a 4.44 second 40-yard dash and posted a vertical leap of 41 inches. Those numbers are a huge reason why Gruden said after an OTA earlier in 2018 that Davis has a chance to "really explode onto the scene" as a second-year player.

If you want physical upside, Davis has it. The team may feel it's too early to give up on a youngster who possesses as much raw ability as Davis does.

His biggest question: Can he do the little things?

At times, Davis' extreme athleticism is evident. At other times, however, his lack of polish is, too.

His footwork can get sloppy, and while players like Harris and Quinn snag nearly everything, No. 19's hands aren't as reliable. That athleticism is tantalizing, but it can only buy him so much time.

Bottom Line

As of now, which is July 31 (five practice days into camp), no one has really separated themselves in this particular group. An injury could change that and the preseason games absolutely will, too.

Ultimately, how many receivers Gruden keeps has yet to be decided. But his decisions of whom to keep will be difficult regardless of how many he eventually does.
