The more Atlanta keeps winning, the more coach Mike Smith keeps tinkering with ways to help the Falcons improve.

Smith’s Falcons are 7-0 and the NFL’s only unbeaten team, but the fifth-year coach still sees a club that’s far from perfect.

“You may not believe this, but you’re in a week to week cycle in the National Football League,” Smith said on Monday. “It really doesn’t matter what happened the week before. It’s all about the next game, and that’s how you have to approach it.”

Nearly everything seemed to work in Atlanta’s favor during a 30-17 victory at Philadelphia on Sunday.

Quarterback Matt Ryan directed scoring drives on the first six possessions. Atlanta’s defense kept the Eagles off-balance all afternoon.

But Smith pointed back to a rudimentary practice session last week that played a significant role in helping his team beat Philadelphia.

Despite the league’s best record, Smith gave his players an entire week off during the bye before he took them back to the field last Monday to work on the basics of football — blocking, tackling and using proper angles to make the right plays.

Maybe the approach sounds too simple, but Smith said the results were evident against the Eagles.

Smith estimated the Falcons spent 45 minutes of “remedial, 8th-grade football” to help everyone restart the season.

Defensive players were retrained to take better angles in pursuit, and Smith believes that’s one reason why Atlanta’s run defense, which began Sunday with the league’s 28th-ranked run defense, had a season-best performance that held Philadelphia to 92 yards rushing.

“We worked on the approach, the fit, where your eyes should be, things that,” Smith said.

Later in the week, defensive coordinator Mike Nolan installed some hybrid looks that seemed to confuse Eagles quarterback Michael Vick.

Reserve defensive end Kroy Biermann, who finished with one sack and seven tackles, lined up at free safety for one play. Nolan also deployed a three-tackle front to start the game in which Jonathan Babineaux, Vance Walker and rookie Travian Robertson were lined up with Biermann — not four-time Pro Bowl selection John Abraham — at end.

“The (previous) two games we didn’t play as well as we could have,” free safety Thomas DeCoud said. “But now we are starting to hit our stride and it’s good to come out after the bye week and get a good solid win under our belts and really play well on all sides of the ball.”

Offensive coordinator Dirk Koetter gave his reserve players a bigger role.

Drew Davis, who spent last year on the practice squad, had his first career touchdown pass. Running backs Jacquizz Rodgers and Jason Snelling took on significant roles to score touchdowns while two-time Pro Bowl pick Michael Turner had a slow day, averaging just 2.4 yards on 24 carries.

During the “remedial” practice, offensive linemen worked on combination blocks. The fruits of that work, including the debut of rookie right guard Peter Konz, could be seen on Rodgers’ 43-yard run that set up a fourth-quarter field and gave the Falcons a 30-10 lead.

Smith and his staff are mindful, too, that they must keep players fresh, not just for an entire game but for the whole season. Since taking charge of the Falcons in 2008, Smith has routinely given veterans, particularly his “over-30” club, as he calls it, a day of rest during the week.
