Dumfries has strong straight-line speed, especially considering his size. He gets up and down the right flank efficiently, allowing him to track back quickly and also push forward to support attacks.

One of Dumfrie's standout offensive traits. His crossing is accurate and powerful, especially when delivering from deeper positions or after overlapping runs.

Defensively, Dumfries is solid. His tackling, interceptions, and ability to read plays make him a reliable presence on the right side.

He’s not the most agile full-back, but he makes up for it with strength and positioning. He rarely gets physically overpowered and wins most shoulder-to-shoulder duels.

Dumfries is built like a tank for a full-back. His 6'2" (188 cm) frame, combined with high strength and aggression, makes him a nightmare for wingers who rely on physical dribbles or cuts inside.

A rare trait for full-backs. His height gives him an edge in aerial duels, especially when defending back-post crosses, a common weakness for many RBs. He can also be an unexpected threat during corners and set pieces.
