The main part or Warner’s statement is the fact that he’s not sure how he would have performed. We can speculate all we want about the Cardinals reaching out to Warner during their playoff run, but we can’t predict how he would have made out.
Warner himself admitted that he strongly considered a comeback had the Cardinals sought his services.
Kurt Warner on playing for Cards: "I would have considered it. … Physically I feel really good. … I don't know what I would have done."
