Colts quarterback Peyton Manning is worried that an umpire in the backfield could disrupt the team's offense. "It certainly doesn't seem like they took some of the things that we do and other teams do into account when they made the rule," Manning said. "I'm not a big fan of it right now." A new NFL rule has placed an umpire in the backfield heading into this season. He traditionally was stationed on the defensive side of the football, behind the linebackers and 4 or 5 yards off the line of scrimmage. This season, he is on the offensive side, 12 to 15 yards deep, set to the left of the quarterback and opposite the referee.
