The people talking about Yamamoto here as if they watch him are hilarious, you really can't judge him based on his size/shots/point totals.
He's a great PKer and a good two-way 5v5 player, and he's NOT AT ALL the soft perimeter player that some people are describing. He's extremely gritty, possibly the grittiest guy on our team after Hyman. He plays much bigger than his size and is great on the forecheck.
Tippett is really misusing him right now though. He's not a good fit with Draisaitl, who plays a heavy cycle game that draws a ton of abuse. Yamamoto isn't bad on the cycle, but his lack of size and elite speed prevent him from creating enough space to create high danger scoring chances. Playing on a line that is built a bit more off the rush would help him like crazy, Tippett just can't see it right now. (Then again, in an interview our assistant coach mentioned that our top players consistently ask to play with Yamamoto). The reason his shot totals are so low is that he prioritizes maintaining the cycle on for Draisaitl. If he stopped deferring to him just a little bit, both his shot and point totals would rise pretty steadily.
