Michael Crabtree today described a divided locker room after Colin Kaepernick supplanted Alex Smith at quarterback as well as the bizarre sight of seeing Smith, the longtime starter for the 49ers, suddenly relegated to backup duty at practice. "I hate to talk about it. But you have the starting quarterback and a couple of weeks later, he's the starting scout-team quarterback," the 49ers receiver said on the Rich Eisen podcast. "And he's taking all the snaps with the scout team. It was kind of crazy to see." Smith and Crabtree have had an uneasy relationship. In 2010 Crabtree intimated that he preferred Troy Smith's go-for-broke approach to Smith's more conservative one. He also seemed to resent the fact that he broke his foot before the 2011 season while taking part in an lockout practice organized by Smith.
