So when the defensive end visited East Lansing last weekend, he took notice of Calhoun throughout the day.
"I love watching him play," he said. "It was so cool to sit in a team meeting right next to him and hear what he had to say to the coaches and about all the film. He knew a ton of the answers and was talking a lot.
"After practice, he was talking to the rest of the D-line how he thought practice. He is a great leader. I enjoyed watching him."
The 6-foot-3, 220-pound Berghorst was on his second visit to East Lansing, so he already had seen all around the facilities.
This time, he took in all that the first spring practice in pads had, as well as the rest of the day.
"We got there and sat it on a team meeting and listened to Coach (Mark) Dantonio speak," he said. "Then they broke up and I sat with the defense while they watched film and learned a lot."
Watching both his positions – tight end and defensive end – during practice was valuable to him as well for what he can take back with him.
"I spent a lot of time watching the D-line and tight ends, my other position and trying to learn a lot of what they do," he said.
Up next will be visits Saturday to Michigan for the Wolverines' spring game, a trip down to South Bend for Notre Dame's spring game next weekend. He hopes to be back at Michigan State for its spring game on April 26.
In between the visits, Berghorst is working hard to get better – and bigger – before next season.
"I'm working really hard in the weight room right now," he said. "I'm 220 right now and I'm trying to play next season around 225-230.
"For my position, I'm working on attending as many camps as I can and combines to work on my one on ones moves and techniques. I'm working on my footwork a lot, too."
