On the other hand he had 17 points in 18 games before being injured. During that time he had an important role. While he was away others returned to the lineup, he got moved down to, at least for a while, 3rd pairing.
A different role can lower scoring on a pts/minute basis, not just total basis. If a player gets to play top pair offensive minutes he'll score more than if he's playing with a 3rd pair guy and defensive forwards with little offensive ability.
So he started out highly ranked, started out the season with a bang, got hurt, came back to a much reduced role and never regained the form he's shown earlly.
In 2015 the Canucks drafted a forward that didn't have big offensive numbers in the USHL-just 30 pts in 50 games. While there was debate, he was generally viewed as not having a huge upside offensively. His ppg was just slightly above what Woo's was this season in the WHL, without the injuries and without the hard hitting. He's turned into a pretty good prospect after winning the 2018 Hobey Baker award.
The Canucks took a flyer on someone whose draft season was derailed by injury. Until we see more of him, we won't know whether the gamble worked out. About all we know now is he did really well in his post-draft interview and doesn't appear to have elite offensive ability.
What will he be like? As my elder son answered several decades ago when asked if he was going to have a little brother or a little sister, "we haff wait see."
