I'm really not sure why everyone thinks it's such a big deal. Because it doesn't look pretty on a stat sheet?
A lot of drafted guys don't go right into the NCAA in their D+1. It's more rare for 1st round picks because they're usually further along when they get picked but it's not a big shocker that this prep school kid was very raw, as everyone expected. Had he been 0.75-0.8 PPG in the USHL or whatever he may have been, would that mean anything for his long-term trajectory? I remember people saying they were shocked when Sam Rinzel wasn't Bobby Orr out there as a 1st round pick in the USHL D+1. Someone on here was like "I was shocked he looked like he belonged" well yeah, he belonged, he was playing high school hockey the prior year and wouldn't be in that league if it wasn't where he belonged. Fast forward and the toolset that got him drafted high progressed along enough to see him be named Big Ten Defenseman of the Year and now he's signed to an ELC and playing end of season burn year NHL games.
He held down a roster spot after a spot unexpectedly opened up, and didn't put up points, but wasn't really expected to. I think playing in a depth role in the NCAA this year probably just makes him better equipped to make a jump next year. The only "downside" if you really think about it is him burning a year of eligibility but they wouldn't want him to spend 4 years in college anyways.
