He thought he was just going to pick up his tickets and go to his seat. What he got, instead, was the red carpet treatment from the OU support staff and got to spend quality time with the OU coaches.
"They really treat you like you're somebody," Glenn said. "I didn't expect it to be that great or to be able to go on the field and watch them warm up."
Glenn is playing defensive end in high school but is being recruited as a hybrid of a defensive end/defensive tackle for the Sooners.
He weighs 285 pounds but said he runs the 40-yard dash in 4.7 seconds so it gives the OU coaches options in what they want to do with Glenn.
Glenn made his first trip to OU's campus in June for the camp and came back later in the month for an unofficial visit and committed. Saturday was the first time he had been able to see the Sooners in person.
"It was great," Glenn said. "They blew them out. It was incredible. They did awesome and didn't take one play off the whole game."
What stood out the most to Glenn was the atmosphere. He said he is not used to seeing so many people care and support the team. He said it's something he can get used to.
"That's one of the reasons why I love OU," Glenn said. "They're loved by the whole community. It was good to see the community out there and having a blast."
Glenn hasn't worked out the details for his official visit, but he said he plans to be at every single OU home game this season and at the Red River Rivalry against Texas next month.
Glenn was the leading tackler in Irving Ranchview's 20-14 win to open the season last week.
