Mantas has demonstrated the ability to shoot effectively from three, both on the move and in catch-and-shoot situations, making him a valuable perimeter threat. He can attack closeouts and get to the rim with straight-line drives, adding an aggressive slashing dimension to his offensive game. Mantas is a willing passer in drive-and-kick scenarios and actively fills the lanes in transition, contributing to his team's fast-break opportunities. However, he needs significant improvement on the defensive end, as he frequently gets blown by, and must work on his ball-handling skills to create more opportunities for himself. Additionally, while he is a willing passer, his decision-making can be questionable, leading to turnovers, and he needs to consistently compete as a rebounder instead of standing and watching.
