I said I would give the positives as well, so I will give my positives.
First off, the thing that Nemec exudes most is confidence. He is insanely confident in every single decision he makes. He carries the puck up with insane amounts of poise that is shocking for a kid who just recently turned 18. He's probably the best puck carrier in the draft. There is no doubt something to be said for that. There is so little panic in his game that it almost looks like he's not even trying half of the time. In reality, though, he is just dictating the pace of play in the offensive zone. In that aspect, he is mature beyond his years. That will make him an impact defenseman almost no matter what.
In terms of his puck carrying, he exudes great body positioning to shield off defenders from the puck and create separation and like I already mentioned, great confidence. He can take the puck up the middle of the ice with ease and is willing to use his nice set of hands and solid edges to evade defenders coming at him. Even though I am praising him, I would just like to mention that his breakout pass needs work. In the offensive zone, his passing is fine, but in transition, for some reason, it just loses its accuracy. As of right now, it primarily seems he will be successful in transition as the primary puck carrier up the ice and into the offensive zone. In this way, he can read the defense and play at the pace he wants to set rather than risking a turnover off of a bad pass.
When he gets into the offensive zone, Nemec is just one of those guys that has a natural feel for the offensive zone. He just knows where open space his and how to get there, both with and without the puck. With the puck, he loves utilizing strong headfakes toward the middle of the ice to then cut outside and free up space for a pass into the slot. He loves using headfakes to freeze defenses and goaltenders to then make a pass for a better scoring opportunity. Without the puck, Simon Nemec exudes a great ability to find soft spots in the defense, these small areas of open ice where he can receive a pass to fire a wicked one timer on net. He kind of glides around creeping up and around the defense until he finally strikes and the goalie didn't even see the puck go past him and into the net. He uses his body extremely well in the offensive zone, especially in terms of deception. His passing in the offensive zone is very solid, much better than in transition, where he completes crisp, accurate passes that fly all over the offensive zone.
These are primarily my positives for Nemec. I would like to point out that he is most definitely not the fastest guy in the draft, something I don't think I have touched upon yet. If he wants to continue to be a dominant puck carrier, he needs to get quicker or else he will get caught by the backchecker more often than he would like.
