The Raiders coaching staff is starting to fill out. The team announced the hiring of four more assistant coaches on Tuesday morning, bringing the total to 10 people working below head coach Jack Del Rio.
Bobby Johnson has been hired to coach tight ends and Tracy Smith will be a special teams assistant under coordinator Brad Seely. They worked together last season with the 49ers.
The Raiders also announced the previously reported hirings of Rob Moore as receivers coach and Bernie Parmalee as running backs coach. These moves complete the main position-coaching staff on the offensive side of the football. They will work under coordinator Bill Musgrave.\

Johnson recently worked with the Lions. He was assistant offensive line coach in 2014, but coached their tight ends in 2013. He coached tight ends with Jacksonville in 2012 and was an offensive assistant with the Buffalo Bills from 2010-11.
Smith worked under Seely for the last three years in Santa Clara. He has also worked for the Cleveland Browns and Seattle Seahawks.
The Raiders have a few openings remaining, including a vacancy at defensive coordinator. The Raiders recently interviewed Louisville defensive coordinator Todd Grantham to fill the position. No hire has been made at that spot as Del Rio continues to evaluate his options.
