Scouting Report: Strengths
  • Duncan has long arms that allow him to survive as a pass protector on the edge, and Duncan typically plays with good balance.
  • Has a prototypical build for an NFL tackle, with a wide frame and long arms. He’s a mauler in the run game, exploding off the snap and winning with leverage and upper-body strength at the point of attack.
  • In the run game, he plays with a mean streak and does a nice job generating a push at the initial point of attack. He can get outside and does a decent job landing blocks in space.
  • He also flashes heavy hands and has the ability to knock back pass rushers. Duncan shows a mean streak as a run blocker, doing solid work on the second level.
  • Big athlete with good bulk and a filled-out frame. Stays balanced and doesn't overextend in pass protection. Stays disciplined with good bend and leverage.
Scouting Report: Weaknesses
  • While he’s solid as an athlete, he’s more comfortable moving forward as a run blocker than setting in pass protection, as Duncan too often relies solely on his initial punch to stand up pass rushers instead of moving his feet.
  • His hands aren’t violent enough to stand pass rushers up early in the down, and often plays with poor balance.
  • Plagued by choppy footwork and a tendency to set too high in pass protection. Duncan generally plays with poor balance, and he needs to improve core strength.
  • As a run blocker, he’s quick off the line but often comes up too high; he struggles to generate movement at the point of attack.
