Why didn't the Oakland Raiders vote on the proposed new collective bargaining agreement? Was it just owner Al Davis' old contrarian approach to league matters as the Raiders were the only club to abstain from voting on the new labor deal in Atlanta? The Raiders have a history of litigation against the league, including numerous lawsuits related to their domain rights and moves back and forth from Los Angeles. Here's the Raiders' explanation to Comcast SportsNet Bay Area via CEO Amy Trask: "We have profound philosophical differences on a number of issues -- both of a football and economic nature," Trask said in an email. "We have consistently expressed our views on these matters to the league." Source: National Football Post
