The Oakland Raiders, responding in a written statement to the filing of a lawsuit against them by the NFL, claimed league officials were "sneaky," "stupid," and, "sick and demented and corrupted."
The Raiders also said they would "bloody" the league in U.S. District Court in Los Angeles, where the suit was filed Thursday in hopes of forcing the team to affirm league guidelines in respect to relocation and revenue sharing.
It is unclear who wrote the unattributed, six-paragraph missive that appeared on Raider letterhead.
Joe Browne, NFL spokesman, said the league would have no comment.
The Raiders were responding to the second lawsuit filed against them by the league in 15 years.
Although the league does not want the Raiders to return to Los Angeles, it hopes the suit will reaffirm NFL franchise relocation rules and collect the $3 million to $4 million annually that the Raiders allegedly owe as part of the league's revenue-sharing agreement.
Even though his move to Oakland was approved by league owners in July, Raider owner Al Davis has threatened to sue the league for not allowing him to move to Oakland last season. He has also refused to share in the financial gains of the new stadium deal handed him by Alameda County Coliseum Commission.
