Quick stopped 25 shots in the Kings' home opener, but the star goalie also misplayed McDonagh's harmless cleared puck from deep in the New York end early in the third period, knocking it into his own net.
Henrik Lundqvist made 28 saves, and Rick Nash assisted on both of Richards' goals for the Rangers, who are opening the season on a nine-game road trip.
Jake Muzzin scored for the Kings, who have scored just six goals in three games this season.
Hopefully [Jonathan] has a year that pushes us, that is the organization, to speak to him next summer and looking for [a long-term contract]. Because the thought process is trying to get a goaltender, and hopefully it's Jonathan, to be the stabilizer for this franchise.
