It actually is more than 4 rookies starting, if you consider that Whitner, Simpson, and Ellison will be playing most of the time, and Williams and McCargo will be rotating on the DL (I'd assume they'll be taking turns rotating, i.e. being paired with a veteran and not together too much, although that did happen a few times last Sunday). I would assume that Ellison will continue at WLB, where Crowell WAS starting, and that Crowell will continue to play SLB until Takeo returns.
