Steelers running back Jerome Bettis failed to make the Pro Football Hall of Fame for a third straight year. This year, Bettis is the only running back among the 15 modern era finalists. Bettis ranks sixth on the NFL's all-time rushing list, which seems to weigh heavily for voters. He failed to make the Pro Football Hall of Fame Class of 2013, which was announced today in New Orleans. Robinson, 71, is the sixth player from Penn State in the Pro Football Hall of Fame and was one of two senior nominees. Joining Robinson was fellow senior candidate defensive tackle Curley Culp, and five modern-day candidates: offensive tackle Jonathan Ogden, offensive guard Larry Allen, defensive tackle Warren Sapp, wide receiver Chris Carter and coach Bill Parcells.
