JACKSONVILLE, Fla. -- Just because the Jacksonville Jaguars drafted receiver Dede Westbrook doesn't mean they're giving up on Rashad Greene.

Though both are slot receivers and punt returners, GM Dave Caldwell said that doesn't mean both can't make the roster and contribute on offense and special teams in 2017.

"I still have high hopes for [Greene]," Caldwell said. "They will play similar type of positions, but we have room to keep both of those guys."

The Jaguars selected Westbrook in the fourth round of the draft last Saturday because he was too talented to bypass. Westbrook was one of the best receivers in the nation last year at Oklahoma but slipped to the fourth round because of off-field concerns: Two arrests for domestic violence (charges were dropped both times, though the second because the victim was unable to be located) and an arrest for trespassing last May.

The Jaguars have told him he has no margin for error in terms of off-field behavior. If he avoids issues there, the Jaguars envision using him as a slot receiver and as a punt returner -- basically the role Greene was supposed to fill after a solid rookie season.

The Jaguars drafted Greene in the fifth round in 2015 and immediately made him their punt returner. He missed seven games with a hand injury but averaged 16.7 yards on 18 returns and took one back for a touchdown. Had Greene had enough returns to qualify to appear in the NFL rankings, he would have led the league by more than 4 yards per return.

He also turned two games around for the Jaguars with big punt returns. His 63-yarder in the fourth quarter set up the Jaguars’ go-ahead touchdown one play later in their 19-13 victory over Tennessee in November. Three weeks later, Greene returned a punt 73 yards for a touchdown to break open a close game against Indianapolis.

Greene was supposed to compete with Marqise Lee in OTAs, minicamp and training camp last offseason to be the Jaguars’ third receiver behind Allen Robinson and Allen Hurns in 2016, but Lee was so impressive from the start that Greene didn’t have much of a chance. He didn't make an impact as a punt returner, either.

Greene averaged just 6.3 yards per punt return and caught just five passes for 32 yards before this season. He also muffed three punts. Greene battled an Achilles injury for several weeks and missed three games and was eventually placed on injured reserve on Dec. 3.

"I think that [the Achilles injury] really set him back," Caldwell said. "I don’t think he ever caught his stride. With a player sometimes you have those issues and you have that adversity, and I think he learned how to deal with that. He has had a great offseason. I saw him in the hallway the other day. He is getting a lot of muscle mass. He has really worked hard in correcting those biomechanical issues that he has had that causes injuries."

After setting the Florida State record for career receptions (270) and career receiving yards (3,830) from 2011-14, Greene has just 24 catches for 135 yards and two touchdowns and has averaged 11.0 yards on 39 punt returns.

The Jaguars didn't go into the draft expecting to take Westbrook, but when he was available when they were making their fourth-round selection they couldn't pass him up. Westbrook caught 126 passes for 2,267 yards (18 yards per catch) and 21 touchdowns in two seasons at Oklahoma. He won the Biletnikoff Award in 2016, which goes to the country’s top receiver, and was one of five Heisman Trophy finalists last season.

Westbrook returned only five punts in his college career, but he averaged 16.2 yards per return and took one back for a touchdown.

"He is a dynamic athlete [with good] speed and with the ball in his hands," Caldwell said.

However, there's still room for Westbrook and Greene to make the final roster.
