Linehan takes over play-calling dutiesBy Jim ThomasST. LOUIS POST-DISPATCH10/03/2007At the start of practice Wednesday, coach Scott Linehan walked over to reporters and confirmed that he will take over play-calling duties starting with Sunday's game against Arizona and that offensive coordinator Greg Olson will be moving up to the coach's booth during games. It was another 180-degree change of heart by Linehan, who on Monday issued a strong defense of Olson as the team's play caller. Olson had taken over playing calling for the final six games of the 2006 season following a shutout loss to Carolina. During that time, the Rams went 4-2 and averaged 28 points per game. But in part because of injuries, the Rams have scored only 39 points this season, the second-lowest total in the league, and have scored only two offensive touchdowns.
