While Mayor Gavin Newsom attempted to resurrect talks with the 49ers' ownership over building a stadium, a state lawmaker said Friday that he would try to bar the team from using the name San Francisco if it leaves town. One day after team announced it was done negotiating with Newsom and was now committed "100 percent" to moving to Santa Clara, team owner John York reopened the door ever so slightly by saying he would listen to any new ideas from San Francisco. But York reiterated that the team was still sitting down with Santa Clara officials. York and Newsom met Friday morning at the prompting of Sen. Dianne Feinstein, a San Francisco resident and former mayor who also attended the meeting.
