INDIANAPOLIS — The Indianapolis Colts won their 16th straight regular-season game, the equivalent of an undefeated season, and Jim Caldwell became the first rookie coach since the NFL merger to open his career with seven consecutive wins thanks to Sunday’s 18-14 victory over San Francisco.

Joseph Addai threw his first NFL touchdown pass and Reggie Wayne caught a career-high 12 passes for 147 yards for Indianapolis (7-0).
San Francisco (3-4) lost its third in a row despite a solid performance from Alex Smith, who made his first start in nearly two years. Smith was 19 of 32 for 198 yards with one TD and one interception.
Three-time MVP Peyton Manning wasn’t nearly as efficient as he has been most of the season, yet finished 31 of 48 for 347 yards.
