While he didn't walk away with offer like he had hoped, he still was able to get a great first impression from the Wolverine coaching staff -- specifically defensive line coach Greg Mattison.
"I think it was a beautiful day," he said on Thursday. "I thought we did well as a defensive unit. I got places to grow and get better. Just coming back starting the summer right with this camp. I like learning from Coach Mattison."
Why does he like Mattison so much? Well, it's the way he connects with you on the field, Swann says.
"He's a wonderful coach to learn from, because he knows so much," Swann said. "He's been in the game for a while. I know a lot about him. Just learning from him, every time I would mess up he would critique my effort and stuff like that. He would then make do it again till I got it right. I can appreciate that out of coach. He's not just a coach, he's a players' coach."
That being said, Swann was adamant that he would welcome a U-M offer at any time.
"I don't know what their plans are, but I would surely appreciate an offer," he said.
"Honestly, an offer from Michigan would be almost mean the world to me," he admitted. "Coming from the Detroit area, my whole family is from up there in Michigan. That's just a place I grew up from -- and that's where home is basically."
Already, Swann has notable offers from Michigan State, Missouri and Kentucky among others. He has already been on campus visits to MSU, Purdue, Vanderbilt and Indiana. He says this summer he would like to visit Michigan, Missouri and Kentucky.
What will he be looking for on those visits exactly?
"The factors on my visits will be if the coaching staff can get me to my full potential, be a part of my plan and make my plan possible to the greatest extent," Swann said. "Academics is a big key factor in my school selection. Other than that, a place I feel like home for sure."
