Re: Ben admits he rushed back too soon
The injury can affect your decision-making if your accuracy deteriorates and your WRs aren't getting open as often as before, leading to frustration and forced throws.
Hell, Peyton Manning was frustrated as hell during the 2005 AFC Divisional Playoff against the Steelers. He started forcing throws, as evidenced by the INT to Troy Polamalu that was wrongly overturned, misreading the defense, as evidenced by the sack he took on fourth down at his own 2-yard line late in the game, and missing open receivers, as evidenced by his last pass attempt of the game, which fell incomplete after being underthrown downfield while he had a short option wide open in the left flat that could have helped the Colts move the chains.
Plain and simple, when QBs get frustrated, they fuck up, regardless of how good they are otherwise.
