We are not "guaranteed" a fantastic player. Who is the best 7OA in the past ten years?
Since 2008:
Colin Wilson - Nashville
Nazem Kadri - Toronto
Jeff Skinner - Carolina
Mark Scheifele - Winnipeg
Matt Dumba - Minnesota
Darnell Nurse - Edmonton
Haydn Fleury - Carolina
Ivan Provorov - Philadelphia
Clayton Keller - Arizona
Lias Andersson - New York Rangers
Quinn Hughes - Vancouver
The worst player on that list is also the oldest one on the list in Colin Wilson drafted in 2008. His high water mark was 20 goals and 22 assists in 77 games back in 2014-15. Fleury has yet to play a consistent role on a stacked blue line in Carolina; Lias Andersson has shown promise, and is only 20. Hughes we know a great deal about considering the discussions last year.
There are some absolutely fantastic top line/pair players and potential sitting on that list. I think Scheifele is probably the best of the list, to answer your question.
Edit: Even Edmonton managed to draft a defenseman(!) who has managed to break out this year with 10 goals and 31 assists in 82 games, while playing almost 24 minutes per night.
