I know everyone loves Makar's offence, but Hughes is pretty clearly the better d-man and is pulling more weight on his team. That probably won't matter but Hughes is the more complete player.
Unless Hughes heats up in a big way it'll probably be Makar. They're pretty damn close but I could see Makar being the sexier pick playing with Mac and all that.
If Hughes makes the all-star team that might sway things a bit.
