What happened: Buffalo released Rapp on March 6 before the final year of his contract. Denver added him Thursday as the preseason roster evaluation continues.
Why it matters: The move gives the Broncos an experienced safety option before final roster decisions. It also ends Rapp's five-month stay in free agency.
By the numbers: Rapp's three-year Buffalo contract included $4.85 million guaranteed and carried a $3.74 million 2026 cap charge.
What to watch: His preseason usage will indicate how quickly he can enter Denver's safety rotation.
