Michael Crabtree says his troublesome left foot feels as good as it has since he was a college freshman in 2007. Crabtree has undergone two surgeries on his left foot. "I'm just feeling good, man," Crabtree said. "It's been a while. It just feels good not to have to go through so many warm-ups, putting on a bunch of wraps and (ointments) just to go out and play." Crabtree caught a career-high 72 passes for 874 yards in 2011, but will have to contend with a more crowded receiver corps this season. He's still the 49ers' wideout to own, however.
