POSITIVES: Hard-working, small-area blocker consistently improving his game. Makes effective use of angles, keeps his feet moving throughout the action and rides defenders from their angle of attack. Alert, picks up stunts thrown by opponents and jolts defenders with good hand punch.
NEGATIVES: Marginal skills in motion. Not a dominant drive blocker who finishes the action.
ANALYSIS: Possessing size and growth potential, Butler's ever-improving game could find him a roster spot as a backup for the strong side.
