"I think it was great," he said. "It was a great game. I was surprised there were that many people there. Overall, the game was a great game. Michigan put up a great fight and won the game."
Cass Tech has been kind to the Wolverines, and Onwenu, who stepped in immediately for the Technicians as a freshman last year, is expected to be one of the school's next top recruits.
On Saturday, he got to see alums like Delonte Hollowell, Thomas Gordon and others out on the field.
"It showed me if I work as hard as them I could be where they are."
Onwenu says he came late, and was not able to speak to the Michigan coaches much. He is also hearing from Michigan State, who he has visited, Ohio State, Tennessee, Alabama and Notre Dame. He hopes to see several more college games this fall.
"I'm going to be going to more Michigan and Michigan State games and I might be going to the Tennessee-Oregon game, but I'm not sure yet."
