CSN Bay Area reports the 49ers are not "remotely close" to new contracts with walk-year players Michael Crabtree and Mike Iupati. That's according to "multiple sources." GM Trent Baalke insists the sides are "going to work at it," but added "at some point, you got to stop negotiating deals and let these guys concentrate on playing football." There's a chance the Niners end up letting both players walk.
