Crabtree Signs With The Niners

PFT is reporting, per Jay Glazer of and Adam Schefter of ESPN, that Crabtree has just signed with the Niners. You can read the article here. Should we be concerned about this when the Niners come to town in December? Should we be concerned about the NFC West title at this point? I think both answers should be yes at this stage. I also feel that Shaun Hill is not that great of a QB yet and he will start showing what I mean in the next few games the Niners play.

What do you all think about this development?
