Miller (6-6, 255, 4.9) was hosted by offensive lineman Jon Skinner, a Pennsylvania native.
"I came in toward the end of practice on Saturday," Miller said. "I was impressed with the way they practice. Things move pretty quickly. I was surprised to see some pretty big boys there."
When asked about the highlight of his visit, Miller said, "Probably my meetings with the coaches. I was pretty impressed with how professional they were. I also really enjoyed the players. Jim Tressel seems like a great guy."
Miller said previously that OSU was recruiting him as a tight end.
"It looks like tight end 100 percent," he said. "The guys they have playing tackle are like 6-8, 330 pounds. They recruit tackles for tackle and tight ends to play tight end. That's something I will take into consideration, although the position thing was not that big of a deal for me."
Miller made visits previously to Indiana and West Virginia. He has one more visit coming to Pittsburgh on Jan. 6.
"I have enjoyed all of the schools," he said. "I am trying to keep an open mind and trying to keep them all even until I make my fourth visit. After that, I will be able to say, hopefully, ‘This is where I want to go.'
"The people at Ohio State were very comparable to the people I met at Indiana. The most important thing for me is the people and the support staff you'll have."
Miller, ranked as the No. 50 prospect in Pennsylvania by Scout.com, had nine catches for 193 yards this year and ended his prep career with 20 grabs for 400 yards. He boasts a 3.99 GPA and scored the equivalent of a 1060 on the SAT.
