What happened: Diggs joined Washington this week, giving Daniels another target as training camp moves toward the preseason. The quarterback is entering his third season while learning new terminology and the purpose behind each play.

Why it matters: Washington is installing the scheme during training camp, leaving preseason reps to establish its rhythm. Daniels and Diggs must build their timing before Week 1.

What to watch: Preseason work will show how often Washington uses motion and under-center formations.
