At 6-foot-5, 270-pounds, Thingstad is being recruited for his play on both the offensive and defensive line. The Cardinals were one of the first to extend a scholarship offer, doing so a day after watching his film.
"I literally sent my film to them the day before, and the next day they offered," he told Scout.com last month. "It just took me by surprise."
South Alabama, South Carolina and Southern Miss have also offered Thingstad, who is also drawing interest from Alabama, Georgia Tech and others. He's been staying busy by visiting multiple schools, making stops at Alabama, Georgia Tech, South Alabama, South Carolina and Southern Miss.
During his stay in Louisville, he toured the football facilities, watched the team scrimmage and met with coaches.
"I enjoyed it so much," he said on Sunday. "There was so much that I liked it is hard to say what I enjoyed the most. It really was overwhelming. It was outstanding, to be honest."
Thingstad spoke positively of his interaction with the Cardinal coaches and was impressed by Petrino's open door practice policy. However, watching the team scrimmage from the sidelines in Papa John's Cardinal Stadium was a favorite from the visit.
"Watching the scrimmage was one of my favorite things," he said. "You can really see the intensity of the team and what Petrino brings to the offense and defense. I really liked how I could walk around and interact with some of the players on the sideline."
He has plans to visit both Georgia Tech and South Carolina for their spring games, and hopes to make a return visit to the Derby City in the near future.
"It's fun," he said of the recruiting process. "I'm trying to see and experience as much as I can. I'm trying to stay open through all of this."
