Saints coach Sean Payton seems likely to open the regular season by throwing a dose of youth and inexperience at the visiting Atlanta Falcons.

As of Monday, 10 rookies - six of them undrafted - and three other players who have yet to be on the field for a regular season snap were on the Saints' 53-man roster.

Some of those players may not be active on Sunday, but the Saints will need several of them to suit up.

Asked if he found it unusual to head into Week 1 with zero regular season experience on more than one-fifth of the roster, Payton said, ''We don't pay much attention to that, really.''

''We look closely at how they're going to fit into the plan, how they're going to play in the kicking game and the progress they made at their position group,'' the coach added.

Receiver Kenny Stills, drafted in the fifth round, made a case during preseason that he might be the best deep threat on the club.

He not only gave opponents trouble with his speed, but also made some difficult catches that required balance along the sideline or the coordination to haul in a deep pass with one hand on a dead run.

Defensive end Glenn Foster, an undrafted free agent from Illinois, had four sacks, five quarterback hits and a forced fumble in the preseason.

Nick Toon, a 2012 fourth-round pick who spent his rookie season on injured reserve, was among the leading receivers in the preseason with nine catches for 164 yards, including a 56-yarder on a deep throw over the top from Drew Brees.

Safety Kenny Vaccaro, the club's first-round pick, made 18 preseason tackles, second most on the club, and looks like a hard hitter.

''The rookies and young guys definitely gave the fans something to smile about in the preseason,'' Vaccaro said. ''Nick and Kenny (Stills) flashed the whole time. Glenn Foster was a beast every game. We've got some young talent that can definitely help this team.''
