Although the Irish fell 31-17, the class of 2013 standout said it didn't put a blemish on his day.
"It didn't matter," the 6-foot-3, 225-pound Smith said. "They put up a fight. They had a few mental mistakes that cost them the game. They were one yard away from tying the game but had a mistake."
Smith, who counts Notre Dame among his seven offers, watched the game with his eye on the outside linebacker position he would play with the Irish.
And he came away with a different appreciation of the school.
"It was great to be able to go to school like that and evaluate them," Smith said. "I like tradition they have there, and I had a good time, and I'll continue to look at other schools."
Smith, whose brother, Rod, plays at Ohio State, will be in attendance next weekend when the Buckeyes host Wisconsin. He also plays to visit Michigan unofficially when it hosts Ohio State at the end of the season.
On Saturday, though, Smith's attention was focused on Notre Dame.
"I had a nice time down there," Smith said. "I got there but I didn't know where to go. I walked around the campus and checked out women's basketball. I got to talk to a couple of the coaches before the game."
Smith said he spoke with assistant Chuck Martin and coach Brian Kelly.
"I got to talk to them individually," Smith said. "They were telling me how good an influence I would be if it went and how I would fit in to their defense."
Smith also talked about the atmosphere.
"The fans are tremendous there," Smith said. "It's great. They support team well. I was into the game. I was evaluating my position and see what they were doing and what weaknesses were."
