"I thought the atmosphere was crazy," he said. "115,000 people, the largest amount of people at one game. They have a crazy fan base and it was a great overall atmosphere."
The 6-foot-4, 235-pound Cornell had visited Michigan before and holds an offer from the Wolverines, but had not seen a game in Michigan Stadium.
"It showed me what Michigan had to offer, academics and football too."
It was also an opportunity for him to reconnect with the staff and their message was clear.
"They all said, we really want you here, we really want you here. We really want a weakside defensive end and that's you."
With offers from across the country, Cornell does not plan to rush a decision and will take more visits throughout the season.
