The 2017 defensive lineman from Grange Park (Ill.) Nazareth Academy spent time working against players two years his senior – something that gave him some nerves, but he came around.
"I had a lot of confidence in myself and the drills were great, the coaches were great and they helped me out a lot," he said. "Once I went through the one on ones, I was a little bit nervous, but once I got into the motion, I did really good."
The 6-foot-1, 260-pound Dunn spent time during and after the camp talking with a bunch of Michigan State coaches, including head coach Mark Dantonio.
"I talked to Coach (Ron) Burton a lot because he visited my school so we have a good relationship there," he said. "I also talked to the quarterbacks coach, Coach (Brad) Salem. He told me I did a really good job and Coach Dantonio, the head coach, he told me I did a really job, too. It was an honor talking to him."
Burton, who recruits Dunn's area, also told him to stay in touch moving forward. It was all in all a good experience for Dunn, who grew up watching MSU among his favorites teams.
"I'm a Buckeyes fan," he said. "I watch a lot of them, Oregon and a lot of Michigan State. Those are the top three colleges I watched growing up."
When he looks at the Spartans, one thing in particular comes to his attention: The defensive swagger.
"They have a lot of swagger and I love it," he said. "They have a lot of fun and they play hard and with intensity and they play with swagger out there."
Dunn also attended camp at Illinois this summer, as well as a couple skills camps. He has left the time feeling like he has gained a lot of experience.
"A lot of veterans, college players and coaches teaching me is a great honor and it's a great experience because they went through the same thing I'm going through right now," he said. "It's a really great pleasure that they are all teaching me."
