Why the Colts don't spend big on corners

Colts coach Tony Dungy played defensive back in the NFL, but he would put his money on pass-rushers over cornerbacks every time. "Bill [Polian] and I talk about that," Dungy said from the league meetings in West Palm Beach, Fla. "If you had that choice, you've got to go with the front people because they are harder to find and they have more of an impact on the game."
The Colts are not lavish spenders in free agency. When they do spend big on veteran players, cornerbacks aren't a high priority. Their scheme requires the front four to get pressure, while placing fewer demands on corners in coverage. Oakland, Denver, San Francisco and Green Bay are among the teams that have spent heavily on cornerbacks, with mixed results. The Packers have great depth on their defensive line, a key to their success on that side of the ball.
I think this applies to safeties as well. That philosophy sounds good to me, and based on how Kubiak and Smith have gone about drafting players (Mario and Amobi early, Brandon Harrison and Bennett on the second day) I think they probably ascribe to this as well. If you can provide a great pass rush with your front four, you can get by just fine with average players in your secondary. Jason David looked pretty good back there for them (the Colts) when they won the super bowl, but a year later he was denounced by New Orleans fans for being horrible. How a player performs is quite dependent on the scheme he plays in, and the personnel around him.
That being said, my point is that I think this team's philosophy is to draft and design a defense that can generate pressure with it's front four, and within that frame of mind an average player like CC should be sufficient in his role.
