The Houston Texans and Philadelphia Eagles made big changes to their rosters this year, adding star running backs Joe Mixon and Saquon Barkley, respectively.
Both players made an immediate impact in their debut games, leading their teams to victory with impressive performances.
Mixon had a huge game for the Texans, racking up the most rushing yards and attempts in the league, while Barkley scored three touchdowns for the Eagles.
It's too early to tell if these two were the best offseason pickups, but their Week 1 performances suggest they will be key players for their new teams this season.
