"It's been incredibility busy and super, super hectic," he said. "There's never been a dull moment."
Spain has primarily played on the left side of the offensive line – typically at tackle – throughout his prep career. But with several left tackles on the East roster, Spain offered to play somewhat out of position at right tackle. The move helped him land a starting spot in Saturday's game.
"It was an adjustment, but I got used to it quickly," Spain said.
The week in San Antonio allowed Spain to develop a relationship with three future UNC teammates – Caleb Henderson, Elijah Hood, and Freeman Jones.
"It was terrific," Spain said. "After about 45 minutes of being with them it seemed like I've known them for years. We did everything together that week. It was really good getting to know them and I can't wait for them to get here."
A UNC promo that played during the third quarter of the game's telecast demonstrated the chemistry the quartet has already developed.
On Sunday the foursome dispersed – though Hood and Spain would quickly reunite in Chapel Hill. While most U.S. Army All-American players returned to their respective high schools on Monday, Spain began his UNC official visit.
"It went great – it couldn't have gone better," Spain said. "I'm really excited about starting off."
Spain has made countless visits to Chapel Hill, but there was obviously a different feel to his official stay.
"The food and transportation [being paid for] is the one thing, but it's a little more involved," Spain said. "They talk about the logistics of going to class and what time workouts are."
Since current UNC players have slowly begun to trickle back onto campus from their winter break, Spain actually had two player hosts – Monday it was Caleb Peterson and then Tuesday it was Landon Turner. In both instances, Spain was able to shadow future offensive linemates.
"It's been awesome," Spain said. "I met them before, but by spending more time with them I got to know them better and build the camaraderie that's necessary on the O-line. I'm excited to feel like a part of the group and they're doing a really good job of making me feel that way."
Spain's chaotic month continued on Wednesday. Less than 24 hours after his official visit concluded, he enrolled in classes at UNC.
"I'm really excited about it," Spain said. "I got all my stuff finalized [on Tuesday]. I'm ready to learn."
Spain is also ready to participate in spring practice, where he'll immediately vie to replace four-year starter and first-team All-ACC'er James Hurst, who is off to the NFL.
"There's definitely a little bit of both excitement and anxiousness," Spain said.
