Mancini is a solid right-handed defender that is all over the ice with the size that you need to play a very physical game, which he does and does well.  He is fast on his skates and often takes the puck into the offensive zone with success. One of his best strengths is his defensive play as he communicates well with his defense partner and pitches in to support his teammates. He always seems to make the right decision when it comes to standing his ground on the offensive blueline or knowing when to transition back into his own zone.  When he decides to stand the line, he gives full effort and can usually get a good hit in or stop his opponents in another way. In his own end, he sacrifices himself to block shots when needed without hesitation.  He is strong on the penalty kill and uses his physicality along the boards to win puck battles and make his mark.  When he turns a play away from his own zone to the offensive zone, he does it with fast and accurate passes to his teammates. Once in the offensive zone, he is not easy to mark because he always keeps his feet moving and makes himself playable for passes and shots, often being unpredictable so the opposing team never knows what he is going to do next. Overall, he is a big player who handles the puck well and isn’t afraid to skate up the ice, playing a confident game many teams desire.
