‘If Allen doesn’t markedly improve his completion percentage, it won’t be because of scheme. The Bills had him throwing a lot of quick passes all spring to get the ball out of his hands. His accuracy on short throws was generally good. But spring football doesn’t prove anything. A lot of a quarterback’s accuracy depends on his ability to recognize and read the defense. If a quarterback is unsure of where to go with the ball, he’s often throwing a beat late, and that’s when you get incompletions.’
