Johnson is 40 years old and on his third separate stint with the Bengals, which tells you everything about his role: pure break-glass-in-case-of-emergency insurance behind Joe Burrow. He was elevated for a Week 2 scare when Burrow was banged up, never actually played, and went right back to the practice squad -- a journeyman doing exactly the job he's paid for.
Strengths: Veteran composure and a strong training-camp/preseason showing (60.7% completion, two touchdowns, zero interceptions) that earned him the emergency QB role.
Weaknesses: At 40 years old with no 2026 regular-season snaps yet, his NFL future is essentially limited to spot emergency duty.
