I reckon Stewart was just trying to body check him. Probably happens 100 times a game without issue, but gets undone by Prestia’s height and extremely poor execution.
I don’t see either Stewart’s action as “assault” like some here want to dress it up as. It was clumsy, but he did not intentionally knock Prestia out. Ridiculous for some to imply that was what Stewart was trying to do. 4 week suspension was right for the act given the outcome.
I would also classify Broads charge the same way. Clumsy, not intentional, but it’s probs 4 weeks.
