i think you're onto something. And ill tell you what it is. Its courage. Rattler is the hero right now, because he may lose, but its not due to lacking courage. Carr flashes courage, gets hot, then flashes not having courage, (KC game) then he gets injured. i think this is why a % of Sains fans turned on DC4. For ex, Drew plus Sean were a courage dynamo. They weren't afraid to "shock the world" week in an week out year after year. And all those Qbs you mentioned, all have extraordinary courage. And that is a rare trait.
