49ers coach Mike Singletary admitted recently that he almost made rookie wide receiver Michael Crabtree cry during OTAs. Singletary saw Crabtree doing a jog-through on the practice field, but he hadn't heard that the rookie was medically cleared. So he went over and told Crabtree to get on the sideline and sit until he gets medical clearance. Singletary said Crabtree got "teary-eyed" because he wanted to be out there. "It impressed me because it showed he wanted to be with the team," the coach said.
