What happened: Waller said he began football-specific training in February after entering his 2025 comeback without a full foundation. He has spent extra time studying Carolina's terminology and writes out the playbook by hand.
Why it matters: Carolina's one-year agreement with Waller added a veteran receiving option only weeks before Week 1. His preparation carries added weight after an abbreviated 2025 season.
By the numbers: Waller caught 24 passes for 283 yards and six touchdowns across nine games in 2025 while missing eight contests.
What to watch: The season opener will show how quickly his preparation translates into a defined role.
