Look at his draft. From the 17th pick down to the 30th pick, no one is outperforming Howden in the NHL. Only 4 of those 13 other guys have played in the NHL to this point and the most "successful" in the NHL is Tage Thompson, another center who has 18 points in 77 games. What should he be doing to justify his position? If the rest of those guys are any indication, he should be in the AHL, where most of them are. If he's in over his head at the moment, he's in good company with every other dude drafted after him other than DeBrincat in Round 2 and Bratt drafted in Round 6.
If he was in the AHL, where he should be, putting up nice numbers, I don't think anyone would be questioning if he looks like a first round pick. But either way, again looking at the draft board, I don't know how you could reasonably make the argument that he was somehow unworthy of the 27th overall pick. Really, go look at it and tell me who is more worthy:
