Both the Colts and Saints are home in their domes this weekend and favored to extend their unbeaten marks to 8-0 as the 2009 NFL season hits the midway point. Peyton Manning and Indianapolis are nine-point chalk at Lucas Oil Stadium when they take on their AFC South rivals from Houston. Down south inside the Superdome, Drew Brees and New Orleans are 13-point favorites to take down the Carolina Panthers.
