It was McMillan's third visit to Ohio State, but first time for a game. The atmosphere at OSU stood out to the 2014 linebacker out of Hinesville (Ga.) Liberty County.
"It is crazy up there and the fans are amazing. Hearing the noise and meeting the fans really stood out to me this time. I got to meet some of the fans and that was great. They have been following me on Twitter, so meet them, that was great. I saw 107,000 people at the game and it was just awesome."
The leader of the Buckeyes is first year head coach Urban Meyer and he took them to a perfect 12-0 record.
McMillan likes the way he is being recruited by Meyer.
"Coach Meyer recruits every prospect differently and he is good at what he does. He talked to me this weekend about being the Brandon Spikes at Ohio State that he had at Florida when he won championships," said the 6-foot-2, 230 pound junior.
"I like how he is with us recruits, he is cool to talk to, and I had good time talking with him. He is doing a great job up there."
The Buckeyes entered the weekend on top of McMillan's list and they did not lose any ground.
"They were my leader before this visit and they are still my leader now. When I am up there, I just see visions of myself wearing that silver helmet and playing for Ohio State.
"It is not just one thing that puts them on top for me, there are a lot of reasons why they are number one for me."
