The No. 1 pick from the 2016 draft wasted no time making a splash in the NHL and also finished second in power-play points, first in game-winning goals, first in shots, and third in ice-time among rookie forwards. Matthews, who would've been eligible for the 2015 draft had he been born just two days earlier, was well-prepared for his rookie season after spending his draft year in the Swiss pro league, and right away was trusted by Mike Babcock to play significant minutes.
