Raiders give CB Amerson big extension

In a tale of rags to riches, cornerback David Amerson has gone from being waived to getting a huge contract extension in 10 months.

In 14 games for Oakland, 12 of them starts, Amerson broke up 29 passes, which was second-best among cornerbacks in the NFL.

Oakland also signed former Chiefs cornerback Sean Smith, who is 6-foot-4, to a four-year contract this offseason.

The Raiders now have a physical duo locked up after changing starting cornerbacks in each of general manager Reggie McKenzie’s first four seasons.
