He had been to Michigan State before, but hadn't experienced anything like what he saw on Saturday.
"It was great," he said. "The stadium was packed and the crowd was live. I also had a good talk with Coach Salem after the game."
Hayes could play running back or linebacker at the next level. The Spartans haven't specified which side of the ball they want him at yet, but he says early communication has gone well.
"[Coach Salem] said it was great having me. He wants me to come to a few bowl practices and that I'll make a huge impact on the system. I replied to him, 'I'm ready when you guys are.' He then said 'great' and he would let Coach Dantonio know how I felt."
Hayes, whose cousin Justice Hayes plays at Michigan, will visit the Wolverines this Saturday for their game against Nebraska.
