The return of a healthy Dez Bryant will greatly upgrade Dallas' receiving corps from a year ago. When Bryant is on the field, he attracts double teams, opening things up for the rest of the Cowboys' passing game.

Terrance Williams, Cole Beasley, Brice Butler, Lucky Whitehead and Devin Street should be able to take advantage of those situations.

So the Cowboys are all set at wide receiver, right?

Not exactly.

When Bryant was injured, the offense clearly lacked another valuable playmaker on the outside. Perhaps Dallas will prevent that from happening again by addressing the position in this year's draft.

If the Cowboys don't trade out of their second round pick [No. 34 overall] there could be some very attractive receiving options there that are too difficult to pass up.

Who could be there?

Here are 10 wide receivers you should know entering the draft.

1.) Laquon Treadwell, Ole Miss.

Considered by many to be the top wide receiver in this class, Treadwell is projected to be a top 20 pick. He turned in an underwhelming 40-yard dash time [4.6 seconds] at Ole Miss' pro day last week, but his game tape is too impressive for his stock to fall too far. The NFL receiver he's compared to most: Dez Bryant.

Expert: "He's a big, physical receiver and does an excellent job in the run game, blocking and securing the perimeter ... then, he catches the football. He's strong with the ball in his hands and he's a really dependable target for an offense. A lot of that has to weigh into your decision as opposed to just, how fast (he ran), or how high (he jumped)." -- Titans general manager Jon Robinson

2.) Will Fuller, Notre Dame.

Fuller was a very productive receiver for the Fighting Irish the past two seasons, catching 76 passes for 1,094 yards and 15 touchdowns in 2014 and 62 receptions for 1,258 yards and 14 touchdowns in 2015. It would be interesting to see how Fuller's speed [a 2016 combine-best 4.32 seconds in the 40-yard dash] would take the top off the defense and open things up for Bryant and Williams.

Expert: "Fuller doesn't check all the boxes with his slight frame, below average hands and limitations with his game-­by­-game production, but he possesses the coveted ability to hit the big play and score touchdowns. My grade might be higher than some, but Fuller has the type of functional speed that can win deep and free teammates up in the intermediate passing game. Look for Fuller to come in and contribute early on as a third receiver." -- NFL.com analyst Lance Zierlein

3.) Josh Doctson, TCU.

Doctson certainly was impressive this past season. In only 11 games, he set school records with 79 receptions for 1,337 yards and 14 touchdowns. The 6-2, 202-pounder has an outstanding catch radius. With his ability to go up and make contested catches, Doctson should make an immediate impact in the redzone for whichever team drafts him.

Expert: "All of Doctson's experience came in a spread offense that didn't ask him to run a full route tree, but he shows outstanding effort on throws in his zip code, expanding his catch radius, contorting his body and finding ways to finish catches - bailed out quarterback Trevone Boykin on a number of errant passes on film. Doctson lacks polish in areas, but has the resilient mentality and on-field skill-set to contribute early and settle into a No. 2 receiver role, drawing similarities to Jordan Matthews when he entered the league out of Vanderbilt." -- NFLDraftScout.com and CBS Sports analyst Dane Brugler

4.) Corey Coleman, Baylor.

Coleman won the Biletnikoff Award this past season, an honor given to the nation's top wide receiver. The 5-11, 194-pounder caught 74 passes for 1,363 yards and 20 touchdowns in 2015. Similar to Fuller, Coleman possesses the speed to blaze past defensive backs, which should open things up for other receivers underneath. Some consider him the best receiver in the draft.

Expert: "Electric playmaker with exceptional speed, quickness and burst. Coleman is a touchdown waiting to happen when he gets the ball on the perimeter. He is capable of turning short passes into big gains with his explosive combination of speed and elusiveness, yet he also torches opponents as a deep-ball specialist. ... Although he has been successful on speed routes, Coleman will need to expand his repertoire to be a long-term star at the next level. In addition, he'll need to convince evaluators that he has a keen understanding of complex passing concepts after spending three years in a simple system." -- NFL.com analyst Bucky Brooks

5.) Michael Thomas, Ohio State.

Thomas [6-3, 212] was the leading receiver on Ohio State's 2014 national championship team. He led the Buckeyes again in 2015. His averages over the last two seasons: 55 receptions, 790 yards and nine touchdowns. Thomas has the ideal size to potentially become a team's No. 1 receiver. His uncle is former Cowboys wide receiver Keyshawn Johnson.

Expert: "Thomas isn't the fastest or most explosive, but he is a good-sized athlete and detailed route-runner with little wasted movements to create spacing at the stem. Although he will need time to adapt to a NFL playbook, he projects as an ideal No. 2 wide receiver at the next level due to his savvy footwork, body control and ball-skills to be a reliable possession target." -- NFLDraftScout and CBS Sports analyst Dane Brugler
