Just days before NFL owners are set to vote on a potential Raiders move to Las Vegas, commissioner Roger Goodell wrote to Oakland Mayor Libby Schaaf and said, in part, that he believes the city has yet to find a "a viable solution" to keeping the team there.
The letter, obtained by ESPN, was sent Friday, the same day the city of Oakland and its partners submitted a revised financing plan for a $1.3 billion mixed-use stadium project on the same site where the team currently plays.
Goodell said the league office reviewed the proposal and still believes there are significant problems with it.
