Yes, the first year is going to be tough on him. It almost always is for college kids. Doubly so as a defenseman learning the NHL game. His rookie season is going to have some noticeable bumps.
But he'll get through it. Kid is going to be a good one for us for a long time.
I'm curious about that...
