The Raiders need a new stadium to replace the antiquated O.co Coliseum and owner Mark Davis reiterated Tuesday to the NFL Network his desire to build on the current site of the 46-year-old stadium the Raiders share with the A's. Or at a different site in the East Bay in Dublin.And Davis added that he has no desire in sharing the 49ers' new 68,500-seat stadium in Santa Clara."I give the 49ers all the credit in the world for getting a shovel in the ground in California," Davis said at the NFL Fall Meeting in Chicago. "That's phenomenal. But we're trying to get our situation right. It's not easy to do."Per NFL.com, Davis said the Coliseum, the lone shared NFLMLB stadium, "poses problems when it comes to repairs and upgrades and the sightlines for football are 'absolutely terrible.'"Commissioner Roger Goodell spoke of the Raiders' stadium issues at the meetings as well."I was out there late last fall and met with some of the officials," Goodell said at his media conference. "Our staff was with the Raiders and meeting with the Oakland officials recently. I think there is a very strong recognition that they need a new stadium. That is going to be something they are going to have to have in that community to be successful going forward. Everyone is working toward trying to figure out a way to do that."They are complicated projects. They have not only financing challenges, but how you do it in the context of the overall development and priorities of the community. Mark (Davis) is committed to try and find those solutions in Oakland. But it takes a lot of work. We all know we have to continue to focus to find those solutions."
