Yes they do, but they also often end up down in the AHL.
Quinn Hughes wasn't good defensively, but he was never awful defensively, simple below average. He was never unable to defend at the NHL level.
Barrie was again, bad, not awful defensively early, and bought himself enough leeway to remain in the NHL after becoming worse as he aged.
Again, this is the floor we're talking about, and you are bringing up Quinn Hughes. Legitimately be real if young Quinn Hughes is your example of Hutson's floor.
I think Hutson is incredibly high upside, and I expect him to be an excellent PP QB and offensive weapon for many years.
But again, given his physical limitations, the FLOOR is that he can't hang at the NHL level.
If he reaches his offensive ceiling and sucks defensively, that wouldn't be his floor. In fact that would be closer to his ceiling, considering you've had him reach his ceiling offensively and in your eyes still be a passable NHL defender.
