What happened: Atlanta finished second in the league Sunday in opponent Total EPA at minus-22.2. Pittsburgh led the category at minus-23.6 after the teams opened the season against each other.

Why it matters: For the Falcons, the number points to a clear early strength after a Week 1 buildup dominated by quarterback uncertainty. For Pittsburgh, the league-best mark backs up the defensive tone of the opener and gives the club an early benchmark heading into Week 2.

What to watch: Week 2 will show whether either defense can stay near the top once the sample moves beyond one game.
