Petrovic was once big time prospect. Had really good profile, high IQ, skilled PG, more of a pure point than combo guard but he can run the team, or in your case probably bench unit. Only reason he wasnt as hot as before are injuries. He had few injuries that kinda derailed his progress but this season he is back and played better than anticipated. He reminded people of player that he was projected to be and had some really good games this season. It took him time to grow into his body and i think that also played a role in him getting injured.
He isnt crazy athletic but he can still push the ball and set others up, think Tyus Jones profile with slighty worse 3pt shooting.
