What happened: Jerry Jones and his son have openly discussed pursuing deals before Week 1. The Rams' offseason acquisitions of Trent McDuffie and Myles Garrett raised the league's benchmark for aggressive roster building.

Why it matters: Dallas' improved defense still has room for reinforcement in the secondary. Any significant addition would come with the club carrying the NFL's highest payroll.

What to watch: Watch whether a fast start moves Dallas from trade conversations to an offer. Arizona could also draw calls as Carson Beck's transition approaches.
