Still, backup running back DeAngelo Williams produced four 100-yard games during all of Bell's absences -- including 127 vs. the Patriots -- and finished the season with 907 yards rushing. Williams is 33 and might not hold up over a long stretch, but for one game he can still produce; the Steelers also have Fitzgerald Toussaint.
It also begs the question how will the trio of Kerrigan, Smith and Galette be used. Many think they'll kick Preston Smith inside on passing downs but that's not necessarily the case. There are a bunch of creative formations that get them all on the field and I'm sure we will see them soon.
