Yahoo Sports NFL on Dont'e Thornton

From the article

Wide receivers coach Zach Azzanni expressed optimism about Thornton's development, stating 'I am pleased he's got a great attitude. He's working his tail off. I saw some improvement today, which was good.' Azzanni noted that Thornton has had rough days but bounced back with good plays, and emphasized that the tape is the resume in evaluating players. Azzanni, a 50-year-old assistant with a maniacal focus on fundamental techniques, uses relentless drill repetition to develop pass catchers—an approach aligned with Kubiak's philosophy that Thornton needs both physical and mental development.
