If this weren't points only, then it'd be Sanderson in a walk.
Points-wise, Hutson likely has the higher ceiling, but there are so many questions to be answered before he can get there. Again, right now, Hutson is (depending what site you look at) is about 10 pounds lighter than the lightest defenseman in the NHL (I think it is Spurgeon). At some point, you can't be tiny and play NHL-level defense. So to even get to the Spurgeon, Samuel Girard level of size, Hutson needs to put on a good chunk of muscle. Can he do that? Probably, but it will likely take his body a few years to get there. Hutson can almost certainly perform his offensive duties at the NHL level, or will be able to do so in a short amount of time. But no coach is going to let a 150 pounder create a huge defensive hole; what is Hutson going to do against Tage Thompson? Most coaches are going to want to see Hutson being able to play some measure of passable defense before he gets the chance to show his offense. And then there's the question of whether adding 20 pounds will change the quickness and shiftiness that gives Hutson part of his offensive firepower.
Contrast that with Sanderson. Yes, he's in the mix with Chychrun and Chabot. But he's here now, he's unquestionably NHL ready, and if things break right, he could get PP1 time with some high scoring forwards.
I don't know what your 2nd round pick is, but I think you have to take Sanderson and let someone else wait years to see if Hutson can make it.
