Everyone looks at VO's numbers and determines that he is weak at ES, mostly because 'anyone' should be able to produce alongside Eichel. For the record I'm super guilty of this narrative too...
However, it'll be interesting to see what he can do in lower role against a slightly lower quality of competition. I suspect he'll have an easier time finding space to operate and we see his numbers at ES rise quite a bit.
Also, I'll just go ahead a restate this here: a player like VO will always post better GF% than xGF% metrics because he doesn't rely on shot quality, or the high danger area, to score goals. So even if he does improve his performance at ES, the charts may not always show it.
