Biography: Two-year starter at guard who began his college career at tight end.
Positives: Strong small-area blocker who fights hard until the whistle blows. Stays square, works his hands throughout the action, and keeps his feet moving in pass protection. Jolts defenders with good punch, controls him once engaged in a block, and works hard until the whistle blows. Solid position blocker who turns defenders off the line.
Negatives: Lacks flexibility and has difficulty handling speedy, athletic opponents. Lacks lateral blocking range. Bends at the waist and over-extends into blocks.
Analysis: Duncan is a hard-working prospect who offers growth potential and has a slight chance to make it as a backup guard.
