Yeah, the other obvious comp that people used around the draft was Tage Thompson. But Thompson played at a higher level in his D -1 year and his DY. Just was more proven at an already higher level.
I didn't love the Letourneau pick at all when it was made - I would have taken Greentree or Chernyshov, but neither are Cs. That said, I didn't expect much from Letourneau this year, so I'm not "that" discouraged by his stats. It's not "great", but you drafted him for what he'll be at 23-24 not what he'll be at 19.
