Whether he retired or was fired, offensive coordinator Bruce Arians is officially no longer with the Pittsburgh Steelers: Despite a second straight 12-4 season, two 1,000 yard receivers, and a running game that averaged 4.4 yards per carry, Arians is out. Now the speculation begins about who will replace Ben Roethlisberger's favorite coach. Pittsburgh Post-Gazette sports writer, Gerry Dulac, writes that since running back coach Kirby Wilson was badly burned in a house fire earlier this month, he is unlikely to be able to take the position as had been expected. So will the Steelers look outside the organization for only the 3rd time since 1969 or will they promote from within? Perhaps current quarterback's coach Randy Fichtner?
