NHL Central Scouting’s Peter Sullivan
“He's a guy that is really tough to play against. Sometimes I think he over-does it, tries to do too much, but he's got all the potential. He can carry the puck, he's a tough kid -- he can fight. He's tough to play against. He can work both ends; he plays both the power play and penalty kill. He's just a solid, all-round defenseman.”

NHL Central Scouting’s Blair MacDonald
"Siemens is a strong, smooth skater with good composure and very poised under pressure. He's got good size and isn't afraid to use it. Duncan isn't overly offensive, but does play on the power play and moves the puck well. He gets shots through and is solid defensively, one-on-one.”
