"When you look at Isaac Bruce, Josh (Morgan) and (Michael) Crabtree, they're all going to play about the same. It just depends on how the game goes and the flow of the game," Singletary said.
--Singletary was asked if he's one of the team's best three receivers or is he getting there? "He's getting there. Obviously, you see the talent there. He's going to play that much faster when he gets it," Singletary said. "He's definitely a talented guy, and once the game starts, we'll see how it goes."
--"Do I expect him (Crabtree) to make plays? Absolutely. That's why he's playing," Singletary said.
--Delanie Walker will retain his role as the 49ers' primary kickoff return man, Singletary said. Arnaz Battle will handle punt-return chores.
