What happened: First-year players for the Buffalo Bills, Carolina Panthers, Houston Texans and Miami Dolphins arrived at their respective facilities on Tuesday to open the summer schedule. The group begins on-field preparations ahead of the veteran players.

Why it matters: The early timeline allows incoming draft classes extra days to adjust to professional schemes. Older roster members will arrive later this month to launch full-squad practices.

What to watch: Teams will host their first full-roster sessions next week.
