The graduate of Thief River Falls (Minn.) High School was taken in the sixth round of this year's draft by the Boston Bruins, but playing with the top under-20 talent in the world is a pretty big leap.
"It's crazy just how quick they can shoot it and stuff compared to the level I used to play at," Gothberg told NHL.com. "It's been a lot with tracking and stuff, had some problems starting out, but now I've gotten into a groove and settled down and I'm able to track pucks better."
Exter has followed Gothberg since last summer, when they were together with the U.S. team at the Ivan Hlinka Memorial Tournament, and he has been very pleased with Gothberg's development.
"Over the course of the time that I have seen him, starting last year, he has a very good skill set," Exter said. "Now he's being able to take that skill and put it to work at a higher level. It's his first time going through that. For me, I'm very pleased with how calm he's stayed and how confident he's played."
