Paul Kuharsky of ESPN's AFC South Blog reported on a story by KC Joyner discussing the state of the Indianapolis Colts ground game. Joyner noted that the difference between a respectable running game and the bottom of the league is relatively small. The separation between the 15th ranked running game and the 29th ranked running game is only a few percentage points of yards per rushing attempt behind good blocking. Joyner believes the additions of rookie tackle Anthony Castonzo and guard Benjamin Ijalana are likely to make up that ground. If he is right, Indianapolis's offense should be as potent as ever. Consider how much more dangerous Indy would be with the option to run on short-yardage, save Manning's arm, and command more balanced defensive attention that allows receivers time to get into their routes. It could be an interesting year.
