"Zachary Senyshyn is an absolutely elite skater, and might be the fastest skater in the draft class. He told Yahoo sports that he has been working with Ottawa Senators skating coach Mark Power since he was 13 years old, and it definitely shows in his game. He has a powerful stride that generates great speed, and the acceleration to reach that top speed in just a few steps. He also has the strength and balance to fight through a check and drive to the front of the net.
This allows Senyshyn to take defenders wide off the rush, and cut to the front of the net. He is deadly when he catches a defender flat footed in the neutral zone and will be behind them before they know it.
The balance also allows Senyshyn to win battles along the boards and to establish position in front of the net. The only downside in Senyshyn’s skating is his agility and edgework. He could work on maintaining his speed while making sharp cuts, and changes in direction to be even more dangerous. This area of his game is not that bad, it just doesn’t live up to the speed and power.
Bruins wanted speed and power in a kid over 6'0", they got him.
