Sullivan is a crafty and skilled lead guard that can create for himself or for others, can score in volume from beyond the arc, and controls the flow of the game with the ball in hand. Sullivan had a strong showing at Cali Live running the offense and playing off the ball to get open looks, with a single game high of 22 points against Pittsburgh, and averaged 17 points per game. Sullivan has solid court vision and decision making to find open teammates off the drive and kick pass, to the diver out of the pick and roll action, up the court to open players ahead of the defense, has active hands and timing to jump passing lanes, deflect passes, or poke the ball out to turn defense to offense. Sullivan has the moves to create space off the dribble, moves well off the ball to get open looks, gets to his shot spots, and is highly efficient with the 3-ball off the catch or the dribble, and is a creative scorer around the basket with the euro-step and reverse lay-ups to evade shot blockers.
