Sarah is a good high post shooter and does a good job of following shots, both from her and others, for putbacks.
Sarah sets very solid ball screens and does a good job rolling to the hoop and keeping her defender on her back. On her catch, she does a good job of gathering herself and not forcing quick shots. Sarah does a great job of getting position on the block and sealing with her defender on her back. She also is capable of stepping out and hitting the 15-18 foot jump shots.
A post with really good size, Sullivan will bury her girl and has great back to the basket moves. With good patience once she does get the ball, she reads the defense and takes what she is given. She can play out of triple threat as well, with a good head fake and drive to the hoop.
