The three-star offensive lineman out of Chanhassen (Minn.) High had plenty to do during his time in town.
"I toured campus, toured the facilities, talked with coaches, saw the offensive line film, talked to [Mario] Cristobal for a long time then talked with [Nick] Saban for half an hour," he said. "Talking to Coach Saban and talking to Coach Cristobal was the best part."
The feedback from the two coaches was plentiful and to the point to Ragnow.
"Cristobal was in love, he praised me a lot more than any coach has and he was [not happy] they didn't get my film earlier," he admitted. "Saban said the whole staff watched my film and loved it, and he hasn't had the chance to see it yet and he doesn't offer kids until he watches their film.
"He said he'll watch it in the next few days."
The rise in attention from the back-to-back defending national champs means plenty to the 6-foot-6, 285-pounder.
"That's crazy, like I don't know how to describe it," he added. "An offer would instantly place them as one of my top schools."
For Ragnow, who has no timetable for a decision at this time, versatility is a selling point for 'Bama or any school on his list.
"They said I'm a tackle type, but I could play all positions," he said.
Though the coaches meant a lot to him on the visit, he didn't ignore the renovations within the football facilities.
"They're first class, the weight room was ridiculous," he said.
