After that, though, life got in the way and McQuinnie, a three-star prospect, had been unable to see the campus or see the Sooners in action until last weekend.
McQuinnie committed to OU when he was at Lancaster (Texas) High but has since transferred to DeSoto (Texas) High in the last month. Not eligible to play yet for the Eagles, McQuinnie took his official visit to OU to watch the Sooners' 38-30 win against Texas Tech.
What did he learn? He will eat. A lot.
"They feed you a lot," McQuinnie said. "You won't go hungry, that's for sure."
McQuinnie said he also used the weekend to get to know La Mirada (Calif.) four-star wide receiver Dallis Todd. Committed to OU since April, Todd was also on his official visit.
"I spent a lot of my first night with Dallis because he got there Friday, too," McQuinnie said. "It was cool to get to know some of the other guys."
At this point in his recruitment, McQuinnie said he didn't have any questions for the Stoops brothers. He was going to have a good time and to escape the drama back home.
The fact he got to see OU take down a top 10 opponent was just an added bonus, but it is definitely something he can get used to.
"It was so exciting because you never knew what was going to happen," McQuinnie said. "It was explosive. I don't know how Aaron Colvin got that interception. When plays needed to be made, we made them."
McQuinnie was hosted by freshman cornerback Dakota Austin, also a product of Lancaster. Austin told McQuinnie it was real hard for him when he first got there. It's a lot of hard work, but it pays off in the end, Austin said.
The visit was the best of both worlds for McQuinnie, who got to see what the campus is like on game day but also got to experience parts of college life without football.
He knew pretty early into the trip it was going to be something special.
"At my hotel on Friday people were already setting up their tailgate party," McQuinnie said. "The game started at 3:45 because of the delay, but by 9 a.m. the fans had taken over the streets. It was crazy."
McQuinnie now has the distinction of being OU's first commit for the class. After going over schemes and coverages, it sure looks like McQuinnie is going to end up at strong safety when he arrives in Norman.
He has never doubted his commitment during this process. And all the visit did was reassure him that everything is exactly the way he wants it to be.
"I was just taking mental notes and getting a feel of everything," McQuinnie said. "I can't wait to get there."
