Nothing positive can ever come from acting violently toward a referee. The player should have been suspended for a long time if he had hit him on purpose. Rewatching the incident, though, makes us question whether the contact was unintentional. The player appeared to apologize and show regret after hitting the referee by raising his arm. A 13-month suspension would be absurd if that were the case. I guess we'll leave it to the pros to make the calls.
