Pastrnak
+ Nice hands, good skating, good workethics, good overall offensive awareness
- Can develop scoring touch further, prone to make a bad pass every now and then, not great defensively.
For the - part, one have to remember that he is a 17 years old playing in a senior leauge, so some parts of his game isnt developed, like defensive awareness. He's not afraid to try to deke and make a difficult pass, obvioulsy he sometimes get burned trying those things against experienced opposition.
Bonus +: He seem to have a great personality from what I've heard. Freindly guy simply put. Material for a good teammate in other words.
