Osemele is a four-year veteran out of Iowa State and started 14 games for the Ravens last season. Their offensive line unit allowed the third fewest sacks in the league with 24 and helped Baltimore set a franchise record for passing yards in a season at 4,271. Osemele started ten games at guard and four at tackle.

In his rookie season of 2012, Osemele started all 16 games at right tackle before sliding to guard in the playoffs, and helped the Ravens win Super Bowl 47 over the San Francisco 49ers.

We have signed cornerback @SeanSMITH24.

Sean Smith is a six-year veteran out of the University of Utah. He was drafted by the Miami Dolphins in the second round of the 2009 NFL Draft. He was an integral part of Kansas City's defense last year, which was one of the best in the league. Smith is a tall, imposing corner at 6'3" and 218 pounds. He will team with David Amerson to form a tandem of physically impressive cornerbacks. Smith has experience in big games as well as playoff games and will surely be an important piece in the Raiders' quest to retake the AFC West division title in 2016.
