Last 3 seasons:
Draisaitl 162 games, 100 goals, 248 points. Pace of 126 points per 82 games
MacKinnon 143 games, 64 goals, 198 points. Pace of 114 points per 82 games
Kucherov 77 games, 38 goals, 100 points. Pace of 106 points per 82 games
Two years ago - Draisaitl outscored Mack by 17 points and Kucherov by 25 points. He also outscored them by 8 and 10 goals respectively.
Last year - Draisaitl outscored MacKinnon by 19 points and 11 goals. Kucherov didn't play.
This year - Draisaitl it outscored Mack by 14 points and 17 goals. Kucherov only 9 games so far.
So he's been better then both of them by quite a bit the past 3 years combined - including each year on its own - in both goals and overall offense. I know Kuch has been great in playoffs and Mack does well too - but not enough to make up this significant gap in regular season.
