Football Nation has learned that the Jacksonville Jaguars have signed another rookie draft pick to its roster. Fourth round cornerback Aaron Colvin came to terms with the team on Wednesday, bringing the number of draft picks signed, sealed and delivered to three. There are six picks left to sign on the otted line, including first round draft pick, Blake Bortles.

According to Michael DiRocco of ESPN.com, Colvin receives a $453,153 signing bonus and the four-year deal is worth $2,673,152.

“Colvin is probably going to begin the season on the PUP list because he suffered a torn right ACL on the second day of Senior Bowl practices. He's likely not going to be cleared for full contact until later in training camp and GM David Caldwell is planning on Colvin getting on the field in the second half of the season, though how much depends on his grasp of the defense.”

The 6-foot, 192-pound Colvin fits the Jaguars' profile for defensive backs and should become the eventual starter opposite Dwayne Gratz.

Colvin could have been a second-round selection had he not had the injury. It was shrewd move by the Jaguars to grab him in the fourth round where many analysts thought it was a steal.

Sullivan happy with receivers on roster

“We will be productive. I’m not concerned with that.”

Those words by Jaguars’ receivers coach should prove there is a light at the end of the tunnel for a unit that was dismantled last season. Jaguars.com senior writer John Oehser said Sullivan’s experience and ability to work with the rookies the team drafted with the roster players already on the team will prove to be a strength this off season.

Sullivan, in his third season as the Jaguars’ wide receivers coach, said he liked what he saw from the team’s early draft selections at the position – Marqise Lee and Allen Robinson – in this past weekend’s rookie minicamp. At the same time, as with any young receivers, improvements must be made.

“They need to learn the control part of the game,” Sullivan said.

That means harnessing natural ability and turning it into NFL production. He discussed Lee first, and said the second-rounder from Southern California has a great first step and speed.

“I just have to teach him some control,” Sullivan said. “I told him, ‘You can’t drive down the street 95 miles per hour and make a right turn. You wind up in somebody’s yard.’”

Of Robinson, a second-round selection from Penn State, Sullivan added, “For a big guy, he can drop his weight. Both of those guys are young and very coachable. They’re good kids and have good character. They’ll be a big asset to our program.”

Lee is penciled in as one starter for the team. Robinson will compete with last season’s starter and team’s leading receiver Cecil Shorts for the other starting slot on the outside.
