The best use case for Svechkov is Phillip Danualt.
I feel like scout's need to do a better job describing Svechkov's offensive skill set and how he creates offense. Specifically, he's got good acceleration, he's an excellent puck carrier and a very smart puck distributor who draws defenders and always hits the open man. Now, combine that with his defensive skill set where he's one of the draft's top puck retrievers and pass interceptors. What do you have? A guy who creates a high amount of even strength offense on the counter attack as well as converts defense into odd man rushes and prime scoring chances as good as anyone in this class. Back to the Danault comparison, that's a big reason why the Tatar, Danault, Gallagher combo was the best statistical line in hockey over the past 3 year despite being centered by a defense first player and flanked by a couple of undersized non-elite line wingers. *Edit: Marchard Bergeron Pastrnak has the same characteristics if you want to level up a bit, though I hate comparing guys to elite players as it's unfair and rarely works out*
Now, does Svechkov shoot the puck well? No. Is he highly creative? Not particularly. Will he ever be good on the powerplay? Very unlikely. But, does he have a great chance of being excellent at even strength? Hell yeah. I think he's might score you 45 points a year (almost entirely at 5v5), kill penalties, drive zone possession and have a great goal differential. I think that's a winning hockey player, and well worth the pick should Dallas decide to go that direction.
That's my bull case for him anyways. I like him a lot more than the typical "high floor" guy.
