How much Ace Sanders contributes to the Jaguars offense is far from being determined. But where he can make an instant impact once the preseason games start next month is as a punt returner.

And do the Jaguars ever need help in that area.

The franchise has only four punt-return touchdowns in 18 years; Sanders had three at South Carolina in three years.

The Jaguars have only one in the last 10 years; Sanders matched that in his last game with the Gamecocks.

Sanders is a big part of the team’s special teams overhaul, which includes several new — and young — faces.

“The great thing about these young guys is they’re so fast,” said kicker Josh Scobee, entering his 10th year with the Jaguars. “They can just fly down the field and make plays. I’m looking forward to seeing them in game action.”

So is new special teams coordinator Mike Mallory. His task is to improve return and coverage units that were among the bottom six in the NFL last year and attain the same consistency achieved by Scobee (25 of 28 on field goals) and punter Bryan Anger (40.7-yard net average).

Sanders is expected to handle punt returns, but the kickoff return job is less clear. Jordan Shipley, Denard Robinson and Tobais Palmer are the candidates.

The Jaguars used nine kick returners and six punt returners last year. They finished 29th and 27th, respectively, and scored no touchdowns.

Enter Ace.

Once he returned from an injury sustained in rookie camp, Sanders showed the kind of burst that will pay dividends.

“It starts with his ability to track and catch the punt,” Mallory said. “I term him more of a north-south type of runner. He’s cat quick and does a good job of finding seams and that’s what we saw on his South Carolina tape. And that’s what we’ll be looking for in the preseason.”

Among the kick return candidates, Shipley has the only NFL experience. Palmer was a big-play return threat at North Carolina State, but Robinson didn’t return kicks at Michigan.

“We’re anxious to see Denard back there and what he can bring,” Mallory said. “He’s certainly exciting.”

The Jaguars haven’t had a kickoff returned for a touchdown since 2007 and have only seven in franchise history.

Things are more stable with Scobee and Anger.

Scobee trails only center Brad Meester in current Jaguars tenure and is the only kicker on the roster.

“I’ve been really impressed with Josh’s work ethic and strong leg,” Mallory said. “He’s a true pro who is always looking to find ways to improve himself and his game.”
