1976–77 Los Angeles Kings season: The 1976–77 season was similar to the year before for the Kings.  Dionne continued to lead the offense, the defense was unspectacular but solid, but it was a season of roster turnover as some aging veterans departed (e.g. Bob Nevin, Mike Corrigan) and others lost significant time to injuries (Larry Brown, Juha Widing, Sheldon Kannegiesser).  Youngsters like Glen Goldup, Lorne Stamler, and Steve Clippingdale struggled although second year defenseman Gary Sargent was solid.  The Kings added Dave Schultz (the "Hammer") to replace Dan Maloney who left in the Dionne trade for toughness, but it took nearly all season for the roster to jell.  In addition, backup goalie Gary Edwards struggled and was eventually traded for Gary Simmons; he was not the answer either, so #1 goalie Rogie Vachon was overworked.
