Dvorsky went 10 SHL games without a single point. Then comes to an OHL team with more than plenty of firepower. It contrasts the strength of the leagues and his ability to adapt to each of them.
For reference, if we're stat watching, Sudbury forward Musty's PPG average is notably higher than Dvorsky's with 10 more points in 1 more game played, and he was drafted 16 spots lower.
Axel Sandin-Pellikka, as a d-man for example, had 0.46 PPG in the SHL (18 pts in 39 games) and was on the verge of breaking a U-20 SHL d-man goal scoring record before the WJC + injury he sustained in it. He was drafted 7 spots behind Dvorsky. Mind you, he played last season in the league, but my point stands.
Not bashing Dvorsky, I just feel he will need more time than others to fulfill a bit longer of a development curve that he has. The patience with that will get the Blues a nice 2C IMO.
