OAKLAND (CBS SF) – Some ten years after the Oakland Raiders lost their Super Bowl matchup with the Tampa Bay Buccaneers, legendary wide receiver Tim Brown told a radio show Saturday that former Head Coach Bill Callahan was responsible for sabotaging the team before the loss.

The Hall of Fame finalist claimed on Sirius XM NFL Radio that Callahan changed the team’s offensive gameplan two days before kickoff of the 48-21 loss in Super Bowl XXXVII.

“We get our game plan for victory on Monday, and the game plan says we’re gonna run the ball,” Brown told Sirius XM NFL Radio. “We averaged 340 (pounds) on the offensive line, they averaged 280 (on the defensive line). We’re all happy with that, everybody is excited.”

Brown claimed Callahan, now the Cowboys’ offensive coordinator, switched to a pass-heavy gameplan the Friday before the game.

“We all called it sabotage … because Callahan and Gruden were good friends,” Brown said. “And Callahan had a big problem with the Raiders, you know, hated the Raiders. You know, only came because Gruden made him come. Literally walked off the field on us a couple of times during the season when he first got there, the first couple years. So really he had become someone who was part of the staff but we just didn’t pay him any attention. Gruden leaves, he becomes the head coach. … It’s hard to say that the guy sabotaged the Super Bowl. You know, can you really say that? That can be my opinion, but I can’t say for a fact that that’s what his plan was, to sabotage theSuper Bowl. … That’s hard to say, because you can’t prove it.”

Callahan was in Mobile, Ala., for the Senior Bowl and did not immediately comment to CBS Sports.
