You're exaggerating. I'm sure he'll be fine. There's something to that player. The Blackhawks don't waste their picks, as a rule. They didn't have many to waste this year.
But my comment/skepticism isn't really about DeBrincat, except that the opportunity for the Oilers to select him would have truly indicated a "new" philosophy in the draft room. That isn't to say Benson is the wrong pick or won't pan out. I don't know. Nobody does.
As a pattern though, this seems to me to be a very Oilers pick in a very Oilers draft. Despite the front office changes, I don't know if this draft - in a very broad stroke sense - is all that different than those of years gone by. A two-way WHL forward, a handful of "cross your fingers defensemen", a goalie picked after the top goalie prospects have already been picked, etc. But maybe the connections here are superficial (and I'm sure they're common to many teams) and I'm reading too much into things because I'm just wary of the Curtis Hamilton song being played yet again.
Still, I don't think it's unreasonable to be skeptical of the Oilers here, at least until their picks start panning out, or they actually do something different at the draft.
