Most interesting storylines for each NFL team as 2025 season begins

Chris Broussard explains why "everything is adding up to a Philadelphia Eagles rout," not a Dallas Cowboys upset in Week 1.

It’s finally here. The start of the 2025 NFL season.

The Philadelphia Eagles will begin their Super Bowl title defense against the Dallas Cowboys on Thursday night. On Friday night, the Kansas City Chiefs will take on the Los Angeles Chargers in Brazil. 

Each of the four teams who are the headliners for the first two days of the season have had some interesting storylines develop over the course of the offseason and training camp. But they are far from the only teams that have dominated the headlines.

Read below for a quick recap of all of the offseason storylines for each team.

All eyes will be on Kyler Murray to see how he can take the team to the next level. Murray has a top target in Marvin Harrison Jr. and a capable tight end in Trey McBride. The offense is built for the quarterback to take the team to the next level but it will be up to Murray to live up to those expectations. Arizona will only go as far as Murray takes them.

It’s the year of Michael Penix Jr. – at least for now. Penix will get the reins as the team’s starting quarterback and it comes with some massive expectations. The NFC South continues to be a wide-open division and the idea of Penix lifting the offense isn’t so far-fetched. Bijan Robinson, Drake London and Kyle Pitts will be expected to take a giant leap and do their part to get the team back to the postseason.
