Despite getting a late start on his college career, Folin wouldn't be there for long.
In 2012-13, Folin skated in 38 games for the River Hawks, scoring six goals and adding 15 assists. He was one of the top freshmen in the Hockey East and landed squarely on the radar of professional scouts.
"I never had an agent and by the middle of my freshman year, my coach told me, 'You should probably get an agent because we got a bunch of teams calling,'" Folin said.
Teams kept calling during the second half of the season - which saw Lowell win the conference regular season championship, the league playoff title and advance to the NCAA tournament for a second consecutive season.
After winning their regional, Folin and the River Hawks advanced to the NCAA Frozen Four for the first time as a Division I program and the first time since it made the 1983 Division II semifinals.
A 3-2 loss to eventual national champion Yale in their first game at the Frozen Four ended Lowell's season, but plenty of NHL teams were ready for Folin to make the jump.
But a conversation with head coach Norm Bazin stuck with him.
"He pulled me aside and said, 'We don't want you to leave, we want you to be a part of our program,'" Folin said. "I told him right away I had no plans of leaving. It never even crossed my mind."
That summer, Folin was invited to a handful of NHL Prospect Camps, as teams salivated with the idea of adding a 6-foot-3, 210-pound, right-hand shooting defenseman.
Convinced he was staying in school, Folin turned down several invites to camps around the NHL. He met with nearly half the League before his sophomore season to get a lay of the land, but was committed to staying in Lowell.
Teams stayed in touch even after the season began. Folin had had enough. With his phone constantly buzzing, he made an executive decision.
"I changed my phone number," Folin said. "I turned them all down and basically told them, 'I'm going back to school.' I told them I didn't want any calls during the season."
Lowell repeated as Hockey East playoff champions and returned to the NCAA tournament, winning 26 games in Folin's sophomore season.
Folin posted almost identical numbers and could no longer fend off the professional ranks.
With offers from almost every team in the League, Folin signed an entry-level contract with the Wild on April 1, 2014.
His two-year stint as Lowell was the winningest two-season stretch at the school in more than 30 years.
