He's slowing down, but that was to be expected. As Hench said, no sophomore defender will be 1 PPGA let alone 2 PPGA except if they're special (which Hughes might be). However, as others have also said UMass's schedule is just effin' weird. I don't know how much college hockey you follow, but Hockey East is like 70% entirely composed of Boston and Massachusetts teams. Compared to 99.9% rest of the NCAA, you play double series every Friday and Saturday. UMass though, has extremely strange days for games like earlier in December where they played one game of the double series on Saturday and the next one on Wednesday because of the close proximity of the teams. On multiple occasions, they've only played one game per weekend. In the end it should even itself out, but the games for that one particular school is really hard to follow.
The only thing I took out of this is you saying Makar isn't special.
