* Bill Polian made one big mistake in Indianapolis: Not having an adequate backup for Peyton Manning. It cost the Colts vice chairman and his son their jobs.
Yesterday, Polian told the Associated Press that not grooming a replacement for the injured Manning was the primary reason the Colts collapsed this season, going from Super Bowl contender to the league's worst record.
"I've always told the staff that our approach should be to hope for the best but plan for the worst, and I didn't do an adequate enough job of planning for the circumstances we were in," Polian said in a phone interview. "It led to this catastrophe."
When asked if he was referring specifically to finding a backup for Manning, Polian said: "Yes."
It's the first time Polian has commented since he and his son, general manager Chris Polian, were fired Monday.
