Rookie linebacker Duke Riley has to cut down on his missed tackles.

“It wasn’t more than we expected in the four games," Falcons coach Dan Quinn said. "The thing that we were encouraged about and we wanted to talk to him about is these are correctable mistakes. Tackling is such a fundamental part of what we do."

The Falcons started working on the tackling on Monday.

"We put the guys right in space and worked some drills at that to make sure we’re going to get that part of our game really intact," Quinn said. "One of the things I really admire about our team is the way they love to compete. If they’ve got something to improve to get better on, we generally shine a light on it and we get a lot better at it."

The Falcons are not too worried about Riley's progress.

"He’s been through it now four weeks, in terms of the regular season, (with) good match-ups and good stuff," Quinn said. "I intend on seeing real improvement on him over the next cycle of games.”
