This week the Pittsburgh Steelers and Atlanta Falcons square off in Week One of the NFL regular season and both teams are hoping to reverse their fortunes on the offensive side of the football. We have been waiting months to see what this Steelers offense will look like and get an idea of just what this team's identity is this season as the Steelers try to navigate one of the toughest schedules in the NFL.

Here are the big storylines to follow this week.

Battle of the aging quarterbacks

Falcons quarterback Kirk Cousins is 36 and Steelers quarterback Russell Wilson is 35 and both teams are entrusting them to play like their younger selves. Which guy finds the fountain of youth?

Can the Steelers slow down Bijan Robinson?

The Falcons have arguably the best all-around running back in the NFL in Bijan Robinson. He's the kind of player the Steelers signed Patrick Queen for.

The workload for Najee Harris

Running back Jaylen Warren says he's hoping to play but if he can't go or is limited, we want to see how Harris handles a heavy workload right out of the gate.

George Pickens as the man

This will be wide receiver George Pickens' debut as the team's uncontested No. 1 receiver. Pickens can do amazing things and this week he'll be doing it while facing constant double teams.

T.J. Watt marching toward greatness

After getting snubbed by the NFL last season for Defensive Player of the Year, we expect T.J. Watt to come out and go right at Falcons' talented right tackle Caleb McGary. This will be a matchup to watch.
