It's an interesting question. I know it's not a satisfying answer but I think this is something where you'd have to actually have an opinion on Puljujarvi beyond "He was drafted high, therefore he's got untapped potential that the Oilers just haven't figured out."
Otherwise, while you're right that there's not a huge hockey cost if Brown goes, I'd have to weigh the actual potential Puljujarvi's got(and his ability to be a functional bottom 6 guy) vs. generally being happy with team chemistry as is.
Not satisfying, but true. Assuming we have nothing better to "spend" Brown on, I'd be interested if the scouts saw enough to be worth the chance. I believe that he'll have to go next year, anyways - I don't think we can afford a 2.1M fourth line player.
Classic low risk, high reward opportunity.
