The Seahawks posted a record of 10-5-1 in 2016, but are once again considered one of the favorites to reach Super Bowl 52. Quarterback Russell Wilson is healthy and slimmer following a rigorous offseason workout regimen and new diet. The Seahawks hope running back Eddie Lacy will help them revive what was a mediocre running game in 2016. The defense should be strong again, particularly with free safety Earl Thomas healthy after suffering a broken leg in 2016.

The Chargers finished with a 5-11 record in 2016, their second consecutive losing season. The franchise relocated from San Diego to Los Angeles in January and will play their home games in the StubHub Center, home to the Los Angeles Galaxy of MLS. The Chargers also have a new coach Anthony Lynn.
