He remembers the finishing touches being put on the Hale Center, the suites being added and the south end zone being closed for the new student section.
The 6-foot-3, 285-pound Miller, who is the younger brother of Oklahoma receiver DeJuan Miller, already holds a Rutgers offer, and has been to campus more than a dozen times. His latest visit was for Saturday's Big Man Academy.
"It's crazy how many times we've been up there throughout me and Dejuan's career," Miller said. "It's good because we've seen the transformation of it from being what it used to be and now seeing how extravagant it is. The suites above the stadium, the new (student section), so it was cool to see that transform."
While Miller is a regular on campus, including making multiple visits for spring practice, this weekend marked the first time he camped with Rutgers, which means it was the first time he was able to receive instruction from the staff.
"You actually learn a lot," Miller said. They make it an experience where it's not like any other camp and you're able to learn and meet with the coaches of the actual Rutgers program, and they break down the film of you.
"They show you the drills that you're going to do before you go out and actually perform them, and then you come back and eat and then you break down what you did on the field."
One of the assets of the camp was Miller's interaction with offensive line coach Kyle Flood.
"It was definitely a great learning experience, and coach Flood is one of the best, and one off the best guys to be around, and always really funny," Miller said. "It was a real good time overall."
Rutgers and Pittsburgh are the two schools to offer Miller, but others are starting to show interest.
Miller is in the process of putting together a summer visit schedule, but is also trying to keep a level head since he is only halfway through his high school career.
"It's weird being this young and having so much attention this early," he said. "I have to remember I still have two more years."
