The Broncos are expected to exercise cornerback Bradley Roby‘s 2018 fifth-year option, which is valued at $8.526MM, according to Mike Klis of 9News. 
That $8.526MM salary will place Roby inside the top-20 in terms of annual cornerback figures, just ahead of fellow Broncos corner Chris Harris. It’s unclear if the 24-year-old Roby is worth that amount of cash, especially given that he’s third in line for playing time behind Harris and Aqib Talib. That rotation doesn’t figure to change much, as both Harris and Talib are signed through the 2019 campaign.
Given the prevalence of nickel packages in today’s NFL, Roby still played on roughly 60% of Denver’s defensive snaps in 2016. But he wasn’t all that effective, as Pro Football Focus graded him as just the No. 83 corner among 111 qualifiers. PFF gave Roby much more positive marks over the course of his first two seasons in the league, so the Broncos will exercise his option in the hopes of him reaching that level of play once again.
The fifth-year option is guaranteed for injury only until the first day of the 2018 league year, so unless Roby suffers a major health issue, the Broncos won’t be completely locked into Roby’s salary for the 2018 season. But as Klis notes, Roby and his representatives could conceivably use that ~$8.5MM total as a foundation in extension talks, basing any long-term salary around that number.
