Langenbrunner believes Lohrei benefitted greatly from the USHL's lengthy schedule, which had most of the league's 14 teams playing between 50 and 55 games.
"For the way the season rolled out as far as the USHL basically playing, I believe, maybe the most games of any league in the world, it was a great opportunity for him," said Langenbrunner. "He got to play a lot of hockey, he got to play in big situations, big minutes, and really blossomed his offensive numbers. He had a good year the year before and he had a really good year this year.
"I think it was really good for him. He's gonna take the next step now to Ohio State. He's been on campus and putting in the work. I think it's been a good path for him. Could he have gone into school? Sure. I think that was a possibility, but I think the path he took is just fine for him."
Lohrei, who checks in at 6-4 and 205 pounds, agreed with Langenbrunner, citing his advancement both on and off the ice during his second full season with the Gamblers.
"Obviously, the whole point in going back was to learn and grow and get better, get bigger, faster, stronger, gain some confidence and experience," said Lohrei. "I think that's what happened. Being there for a second year was awesome, taking a leadership role and doing my best to guide other guys…and improve myself."
Bruins general manager Don Sweeney praised Boston's scouting department for its work in identifying Lohrei - who many expected to go later than the second round in last year's draft - as a player worth investing time and effort into developing.
"I'd like to give our scouts all the accolades in terms of recognizing that he had a longer path of development, that he was obviously growing, he hadn't played the position," Sweeney said while pointing out that Lohrei had previously been a forward.
"There's a bunch of things to put into context in terms of where he is today and how much room he still has. We're excited. There's a long way to go for Mason but it will be a nice challenge for him to go to Ohio State and play against bigger, stronger players…faster. But he has attributes, pace with the puck, offensive blue line confidence, running a power play, the long stick and the ability to defend.
"I think he took that to heart this week, the things that our coaches were getting him to understand how much harder it is and how much more competitive you have to be on pucks in the defensive zone but without taking away his creativity offensively and moving pucks and getting into the offensive flow."
