I don't understand this "go out and find a great quarterback and be aggressive" confusion.
Everyone is aware this is a rebuild year and we have no money. Has something miraculously happened mid season to dump money in our account? Check out the 49ers cap (and ours next year!)
We did have another backup who had an unexpected personal issue. It's difficult to come off the street and learn the playbook enough to be effective. Counterbalanced with the chance of Stafford coming back and the offset of possibly having to knock another decent player off our roster just for 1-2 games. Only the Rams staff have a clearer idea of what is going on and I'm betting we would all agree with their actions if we were in the room listening to the actual facts.
