None of the players here are true superstars yet, but some have the potential to be. Trocheck, Burakovsky, Bjorkstrand, Strome, Gurianov, and Hanifin are a little bit of a stretch, but they are overshadowed by others on their respective teams that have that superstar status.
I think you adhered more closely to the "no superstars" rule than I did I don't think any case can be made against your selections on the grounds I mentioned! Only thing is I think you'd have to flip Oleksiak and Bear to keep to the "play their current roles" rule. Good job and thanks for giving the thought experiment a try!
