This Sunday, the Pittsburgh Steelers (4-2) and New Orleans Saints (2-4) square off in Paris as part of the NFL International Series. For the Steelers, this is a must-win game as the team nears the midway point of the season in a three-way tie at the top of the AFC North.

Here are the big storylines for this week's game.

Germie Bernard the sequel

Last week, rookie wide receiver Germie Bernard had a breakout game with 11 catches as he moved into the starting lineup. This week we want to see Bernard make some plays downfield and not just work as a possession receiver.

Travel plans carrying over to the field

The Steelers and Saints took very different approaches to their travel to Paris with the Saints getting a significant head start. We want to see which team benefits more from their travel choice.

Pass rush the key to slowing down Tyler Shough

The Saints offense revolves around quarterback Tyler Shough, who is a young star in the league. The lack of a run game in New Orleans should be a huge edge for the Steelers pass rushers, who have been inconsistent this season.

Steelers offensive tackles are on notice

Speaking of pass rush, the Saints have a tremendous pair of edge defenders in Chase Young and Carl Granderson. This turns up the heat on Pittsburgh offensive tackles Troy Fautanu and Max Iheanachor, who have been hit-or-miss the last two weeks.
