The Raiders waived linebacker Rolando McClain on Friday, less than three years after drafting him eighth overall to be the centerpiece of their defense.
McClain was mostly a disappointment in Oakland. He struggled during his first two years and then clashed with coach Dennis Allen and his staff last season. McClain was suspended for two games for conduct detrimental to the team and did not play the final five games.
"I'd like to thank the Raiders for giving me an opportunity to play in the NFL," McClain said in a statement. "I'm disappointed that it hasn't worked out better, but I'm very excited and thankful for the Raiders allowing me to get a fresh start."
McClain still had two years left on his $40 million, five-year rookie contract.

Rutgers AD resigns
Rutgers' coaching scandal spiraled deeper after athletic director Tim Pernetti, an alumnus who played tight end for the Scarlet Knights football team, resigned over his failure to immediately fire men's basketball coach Mike Rice, who was caught on video hitting, kicking and taunting players with anti-gay slurs at practice.
The video was shown Tuesday on ESPN, prompting outrage nationwide. Rice was fired Wednesday by Pernetti, but the athletic director immediately came under criticism for only suspending and fining the coach after the video was brought to his attention four months ago.
Pernetti said Friday he wanted to fire Rice on the spot but did not because the consensus among school officials at the time was that it didn't warrant dismissal.
