Accuracy is a big deal. Look at it this way, Shane had a horrible Oline in high school so many people attributed his accuracy issues to that. Going to the E11 camp and not being able to check down is an issue because he didn't have to worry about being sacked. I feel like he felt he had to prove something and tried to fit balls into tight windows with his arm, something that will burn him in the future.
