Butler trimmed down and became a faster, more impactful player with increased range and better coverage. The three-time captain is the heart and soul of his defense and flies around looking to make a hit. He's inconsistent at diagnosing the play, and his lack of length and poise stymie his finishing rate as a tackler. Butler's toughness, cover talent and potential to help on special teams gives him a shot to make a squad despite his lack of physical traits.
