If the Kings’ bus is headed anywhere, there’s a great chance that it’ll be Brandt Clarke driving it. Last season, no Kings player had a stronger impact in terms of on-ice goal differential. Clarke’s production on the back end was heads and shoulders above his fellow defensemen, all while he led the club in blocked shots despite not playing on the penalty kill. On Friday, Clarke, 23, put pen to paper on a five-year extension worth $7.4 million per season.
