The Long family resides a few doors down from the 2014 Wheaton (IL) North quarterback. Chuck Long holds most of the major passing records with the Hawkeyes.
"My parents know his parents pretty well," Thorson said. "It's actually pretty cool."
On Saturday, Thorson saw his first game at Iowa's Kinnick Stadium. Long won a lot of games there and compiled a 35-13-1 record as a Hawkeye starter.
Long, a first-round NFL draft pick by Detroit, was lightly recruited out of Wheaton North. Thorson hasn't received a lot of attention yet, either, but he picked up recent offers from Iowa and Northwestern. Northern Illinois also has been in consistent contact, he said.
"I had a great time on the visit," Thorson said of Iowa. "It was really great to see a game in Kinnick. It's such an amazing atmosphere."
Thorson camped at Iowa during in June and caught the eye of the coaches.
"I think it was one of my better performances of the summer," the 6-foot-4, 195-pounder said. "I connected with the offensive coordinator (Greg Davis) and I really like Coach (Lester) Erb (who recruits Illinois)."
Thorson describes himself as a pro-style quarterback. That fits with Iowa's M.O. for the position.
"I'm definitely a pass-first guy," he said. "But I'd like to think I can pull it down and go if I need to."
Thorson said that he is in no rush to make a college decision.
"I'm looking for a great fit to spend the next four years of my life to set me up for the rest of my life," he said. "I want it to be a place with great football and solid academically. I'd like a great campus atmosphere where I can get involved in some sort of Christian organization outside of football."
Thorson is leaning towards a major in business with a focus on economics.
"I'm not really thinking of any specific time to make my decision," he said. "I guess I'm sort of playing it by ear."
If Iowa ends up being his choice, Thorson is not intimidated by the Long comparisons.
"I didn't really grow up knowing much about him," he said. "I started to learn more in the last few years. I really think it's pretty cool."
