Las Vegas Raiders head coach Klint Kubiak recently said that to reporters after a training camp practice. Raiders rotate Caleb Rogers in with Jackson Powers-Johnson for 1st-team RG reps at training campEarly reports from training camp indicated that Burford and Powers-Johnson ate up all of the first-team reps. "Spencer is a guy that's got some really good film in San Francisco," Kubiak said. "He's come here and has gelled well with our system, and is a big part of this guard competition." If that means Powers-Johnson at right guard, so be it.
