Mallaber is a smart, gritty Upstate New York defender who combines toughness with high-level lacrosse IQ. He understands team defense concepts at an advanced level, communicates effectively, and always positions himself to make the right play. At 6’2”, he moves exceptionally well; his footwork, speed, and timing allow him to match up with top attackmen and win one-on-one battles. Mallaber brings a blue-collar edge to every possession, playing with the intensity and discipline that define Upstate lacrosse. With his athleticism, instincts, and pedigree, he clearly projects as an ACC or Big Ten caliber defenseman.

An imposing lefty from Rochester who occupies a ton of space around the crease, Mallaber checks a lot of boxes and was one of the more well-rounded defenders at the event. Due to his size, he’s able to match up well 1v1 with big, physical dodgers, but he also has the high-level footwork to match feet with the smaller and more fleet-footed ball-carriers and give them trouble. Making a great approach to the ball every time, he’s fundamentally sound and moves with fluidity. He’s a great communicator and man-conscious away from the ball, uses his length in the passing lanes, and has ample stick work that allows him to be an asset on the clear.
