Kieffer is a poised and polished attacker whose smooth movement immediately stands out. Her lightning fast split dodge allows her to switch from right to left almost instantly, while her high cradle protects her stick and creates a difficult release point for defenders and goalies to track. Once she gets downhill, Kieffer can rip the ball with legitimate power. She moves fluidly through traffic and displays an advanced understanding of timing and spacing, consistently recognizing when to cut, slip, or set up a teammate. Kieffer also uses her height effectively, contributes on the draw circle, and applies relentless pressure on the ride. Her combination of stick work, vision, athleticism, and offensive IQ makes her an exceptionally well-rounded threat.
