What happened: The 28-year-old signed the day before veterans reported to training camp. He produced two sacks, including a strip sack, and four defensive stops against the run.
Why it matters: Johnson paired speed around the edge with a power rush against tackles and chip blocks. That range gives Las Vegas another option in its regular-season edge rotation.
By the numbers: Two of Johnson's five pressures became sacks, a 40% conversion rate. His 90.2 PFF defensive grade tied for second among NFL edge defenders.
What to watch: His early defensive snap share and work against the run will show how quickly the preseason production translates.
