Line-by-line combined goal totals for the Kings.
Line 1 (King-Kopitar-Carter): 38 goals
Line 2 (Brown-Stoll-Williams): 27 goals
Line 3 (Frattin-Richards-Toffoli): 17 goals
Line 4 (Clifford-Lewis-Nolan): 8 goals
That's 90 combined goals from the Kings' top 12 forwards. They have an additional 2 goals scored from players outside of the top 12, one from Carcillo who has since been traded, and the other from Tanner Pearson.
You know what that number of combined goals by the 12 Kings' forwards averages out to over the 44 games the Kings have played? 2.04.
For comparison, let's look at how the Ducks forwards are doing. I'll go over their lines used most often throughout the season.
Line 1 (Penner-Getzlaf-Perry): 54 goals
Line 2 (Palmieri-Bonino-Selanne): 29 goals
Line 3 (Cogliano-Koivu-Silfverberg): 27 goals
Line 4 (Winnik-Perreault-Maroon): 13 goals
Extra Forwards (Etem, Beleskey, Smith-Pelly, Jackman, Holland [traded]): 12 goals
That's 123 goals for the Ducks' 12 regular forwards, or 135 goals with all of their forwards combined. That averages to 3 goals per game over 45 games for the Ducks.
