Gurley has the knees of an 83-year-old retired steelworker, he's not a viable option.
I think Moss/Singletary are fine backs. My problem lies with our linemen. Besides Brown (who had a poor game last night but is showing a lot of promise), Dawkins (again, awful showing last night) and maybe Morse, we have very little in the cupboard. Feliciano is overrated as hell and Williams is a backup.
