Though the Raiders could be tempted to move Adams back to safety following Johnson's injury, it would be a bad idea. Firstly, Adams is thriving at linebacker, and defensive coordinator Patrick Graham has been pleased with his acclimation. Secondly, the aging defender no longer possesses the athleticism required to play a coverage role at safety.

Raiders safety Lonnie Johnson Jr. broke his right leg in Las Vegas' mock game on Saturday, a person with knowledge of the injury told The Associated Press.
