Michael Crabtree has been San Francisco's most targeted wide receiver in each of the four games he has appeared in, but he isn't laying claim to the title of number one receiver. "If everybody is making plays, then that's teamwork," Michael Crabtree said. "I think that kind of stuff really gets teams in trouble," coach Mike Singletary said about number one or number two receiver labels. "You start thinking more about, 'I'm the go-to guy.' And we don't want that. We want the team concept, and we are going to keep that concept going forward."
