True. The US legal system to blame for that. Watson got a deal and plead no contest after pushing his gf in an argument. Voynov was found guilty with no plea, after the investigation found blood in different areas of the house. The NHL suspended both until their trial were over. Watson got probation and not much else, Voynov was found guilty and got jail time and as a Russian, Voynov could have been deported if he did not leave and if that happened he likely would have been denied entrance to the US anyway. Can't play in the NHL if you legally aren't allowed to enter the US.
Watson is an American, they can't kick him out and his plea bargain probably makes it so he can still travel to Canada.
Very different situations, even if at the top level, both were arrested for roughing up their partners.
False. Voynov also entered a no contest plea, to the same exact charge as Watson.
