Chara was administering a late hit from behind and got the interference call. But the hit was a shove into the boards at a very dangerous place . A place that every player was aware of, but Chara disregarded the obvious danger and proceeded to punish a player who had earlier pissed him off ( Max wasn't even going for a breakaway, there was another man back). So the biggest player in the league has just possibly ended the career of a promising young player. I say he should be suspended for the season including the playoffs ( depending on if and when Max returns) and be reconsidered next year for worthiness to play in the NHL.
