The Oakland Raiders opened free agency by signing two consensus top free agents.

The Raiders swooped Bruce Irvin from the Seattle Seahawks via a contract that will pay him a guaranteed $12.5 mill. in his first season.

Irvin penned a farewell to Seattle, but he joins a Raiders defense that features All-Pro linebacker and defensive end Khalil Mack.

Irvin joins former linebacker coach Ken Norton Jr., who is the defensive coordinator in Oakland. The 28-year-old registered 22 sacks in 58 career games. He brings his own versatility with an ability to play linebacker or defensive end.

Speaking of versatility, the Raiders inked one of the best and most versatile linemen on the open market.

Oakland signed Kelechi Osemele from the Baltimore Ravens.

Although Osemele signed the richest contract for a guard, he may end up at left tackle for the Raiders. Osemele started a few games at left tackle, as well as guard, for the Ravens.

Last year’s starter at left tackle, Donald Penn is exploring his options in Free Agency. However, he said the Raiders could still bring him back even after signing Osemele.

The Raiders should officially announce the Irvin and Osemele signings when both arrive in Oakland tomorrow.

Meanwhile, the Raiders are also lead suitors for former Kansas City Chiefs corner Sean Smith.

Adding Smith would be major for the Raiders’ reconstruction of their secondary.

Expect the Raiders to continue making headlines as Free Agency continues.
