At no time from 2002 to 2014 did the Colts fail to win an AFC Championship for a period lasting longer than two seasons. During that stretch, Indianapolis won eight AFC South championships and had a streak of five in a row from 2003 to 2007. The current four-year drought is the worst stretch over the last 17 years and has seen the Houston Texans establish themselves as the team to beat in the AFC South.
It is fair to note that the Texans benefited from injuries to Andrew Luck and Peyton Manning during some of those seasons but every team deals with injuries, and Indianapolis didn’t have a strong enough roster to overcome the loss of their franchise quarterbacks for any extended period of time.
