With all the money spent this offseason,  with so many young, talented players, the Oakland Raiders signed breakout cornerback David Amerson to a four-year extension on Tuesday. Mike Florio of Pro Football Talk reported the full details of Amerson’s deal that is worth a maximum of $38.38 million with a $5.5 million signing bonus and $12 million in rolling injury-only guarantees.

Amerson’s deal represents what Raiders general manager Reggie McKenzie has been giving out in “prove it as you go” deals. After getting claimed off waivers last season after a failed career with the Washington Redskins, Amerson went on to set the Raiders’ franchise single-season record with 26 pass breakups. He also had a career-high 62 tackles and four interceptions. He had one year left on his contract so the Raiders locking up one of the best cornerbacks they’ve had in awhile for the next three to four years. Free agent signings Sean Smith and Reggie Nelson are going to help Amerson and first-round draft pick safety Karl Joseph to help solidify a Raiders secondary that could finally give out some abuse to opposing offenses compared to the status quo.

Being financially secure is a major bonus so now Amerson and the entire Raider defense can move together into training camp with no real question marks besides former All-Pro linebacker Aldon Smith’s status once his suspension is up. If he can improve his play going into a full season compared to the 14 games he played in his first season with the team the pass coverage, pass rush and overall defense should continue to improve.
