The preseason for most people is like the previews at a movie theater; they may provide momentary entertainment but the reason you're really sitting through them is because you're waiting for the real thing.
The Colts have basically taken that stance since 2005 or at least it seems that way. Evidenced by the total of four preseason wins in that span and the seven consecutive regular seasons with at least 12 wins.
Either way it doesn't matter because every Colts fan knows that come September through February the Colts will be amongst the elite.
In this preseason finale there are really only two goals, to stay healthy and determine the final pecking order for the regular season. To win in the NFL you have to for the most part do four things; put talent on the field, keep that talent healthy, provide depth for that talent and execute.
Execution on offense is rarely a problem for Peyton Manning and the Colts offense. The Colts' front office has done a tremendous job over the years putting quality talent on the field and finding depth.
Indy like most teams encounters injuries and they have been a major concern over the years. Guys like Bob Sanders, Dwight Freeney and Dallas Clark have been inflicted with a variety of bumps, bruises, breaks and strains. So when such things happen as regularly as they do for the Colts, it is important to have talent to act as a stopgap until the starters return.
