Reggie McKenzie may still be on the hunt for talent on the offensive line, but he is continuing to drastically improve the Raiders defense with quality veteran pickups as another defensive linemen and cornerback will be making their way to Oakland for next season.

Friday evening the Raiders announced they signed cornerback Tarell Brown from the San Francisco 49ers and defensive end Antonio Smith from the Houston Texans to continue their spending on proven veterans.

"The Oakland Raiders have signed unrestricted free agent DL Antonio Smith, General Manager Reggie McKenzie announced Friday.Smith was originally selected by the Arizona Cardinals in the fifth round (135th overall) of the 2004 NFL Draft.  He spent his first five years with the Cardinals before signing with the Houston Texans, where he has spent the past five seasons. Smith has played in 140 career games with 117 starts and registered 324 tackles (229 solo), 41.5 sacks, 10 forced fumbles, 11 fumble recoveries and nine passes defensed.In 2012, Smith was selected to his first Pro Bowl when he set career highs in tackles (51), sacks (seven), forced fumbles (two) and passes defensed (three), along with helping the Texans clinch their second consecutive AFC South crown.

Expect more moves over the weekend, particularly addressing the need for another offensive lineman. These two additions are another promising sign that the team’s roster building is heading in the right direction after the initial panic at the start of free agency. Buying quality veterans and staying clear of big names the Raiders are improving steadily through free agency without making too many risks on their salary cap future.
