The long-running title of this in-game NFL reaction piece is Booms and Busts.
For the early window of Sunday's Week 1, we could have easily changed it to Busts and Busts.
It's generally a question of rest versus rust when the NFL hits the opening weekend, as modern strategy slants toward resting primary players through most (perhaps all) of the preseason schedule. With that in mind, often it takes time for offenses to find their rhythm, for skill players to spread their wings.
Rust was the winner in Sunday's first eight games. Several signature players and offenses underperformed, and seven of the games fell under their posted total.
