49ers general manager Trent Baalke doesn't know the specifics of the Michael Crabtree-Alex Smith feud. However, Baalke, who like every general manager has been barred from contact with players during the NFL lockout, isn't concerned about the situation. "It doesn't bother me at all," Baalke told The San Jose Mercury News. "It's like any relationship, right? When you're growing up with your family, your friends, there's going to be disagreements. There's going to be arguments. There's going to be fights. Those things happen, especially in a competitive environment, which these guys are in. "So when these guys have a little spat here or there or have a little disagreement, that's part of it. They're grown men. They'll figure it out."
