McDavid, who turned 21 on Jan. 13, is the youngest player to win back-to-back Art Ross trophies since Wayne Gretzky was 13 days younger in 1981-82 when he won his second of seven straight with Edmonton.
"That's pretty special, yeah," McDavid said. "That's some pretty good company to be a part of. It definitely means a lot. I've got my teammates to thank for everything, they were helping me a lot down the stretch and doing everything they can."
McDavid, who had 100 points (30 goals, 70 assists) in 2016-17, is the first player to win the award in back-to-back seasons since Jaromir Jagr won four in a row (1997-98 through 2000-01) for the Pittsburgh Penguins, and his 108 points are the most by a scoring champion since Evgeni Malkin had 109 (50 goals, 59 assists) in 2011-12 for Pittsburgh.
At the All-Star break on Jan. 25, McDavid was tied for 10th in the NHL with 54 points, 10 behind Kucherov, but he led the League with 54 points in 33 games after the break.
