If Justin Williams is playing in a Game 7, you should just assume at this point that he is going to score a goal or do something else positive for his team.
For Williams, it's his sixth career Game 7 goal (to go with five assists) in six games, which is obviously a pretty good pace. Here's a look at his latest big-game goal, via @MyRegularFace.
Williams gets a lot of attention for all of this elimination-game goals, but let's not forget that he's a pretty good player in other games, too. Since being acquired by the Kings as part of a multiple-team trade during the 2008-09 season, he's been one of their most reliable players, consistently scoring at a 20-goal, 50-point place and playing a steady two-way game.
