Burmistrov reminds me more of Grabovski than a Datsyuk. No idea where the Datsyuk comparison came from. When Datsyuk came into the league his skill level was unparalleled to any one in the game, the same cannot be said about Burmistrov.
In fairness Pavel was 23 or 24 when he broke into the NHL and didn't become dominant until his late 20's. however, it's more of a style comparison and I think its why the term "poor mans" Datsyuk gets used. There is only one Pavel Datsyuk.
