Ben Simmons leads 76ers and all rookies in assists. He's averaging 8.1 on the season and 10.6 during last 5 games (the same during March overall).
The catch here is that his best "assist partner" Embiid is OUT and Ben will have to create more shots for himself now.
His assist number is a bit inflated during last games, as 76ers are 10-0 during last ten games and scored 115+ in most of these. They should not have such an easy game on offense in Detroit and Embiid absence makes me think that correct line for Simmons assists is ~ 9.0
All season stats: only 16 over 10.5 assists, 60 under.
