Having enrolled in January 2006, Boren (and roommate Brown) were available to participate in 2006 Spring Football.
Both players participated in spring practice, which was part of a national trend of more high schoolers enrolling early.
 Although early enrollment had been occurring for several years, Kevin Grady had been the first at Michigan in 2005.
 
As a freshman during the 2006 NCAA Division I FBS football season for the 2006 Michigan Wolverines, Boren was injured during training camp, and he did not dress in the season opener.
 He had suffered a broken leg.
 Despite being injured through the entire month of September, Boren decided not to redshirt and debuted during the Paul Bunyan Trophy rivalry game against Michigan State on October 7.
 Two weeks later, when Rueben Riley got injured against the Iowa Hawkeyes, he played the entire second half.
 On October 28, with Riley still injured, he became only the fourth true freshman to start on the Michigan offensive line in the modern era during a victory against Northwestern.
 The following week against Ball State, Boren saw action after Jake Long got kicked in the helmet.
Boren's final action of the season came against the Indiana Hoosiers on November 11.
During the 2006 season, all of his appearances were at guard.
During 2007 Rose Bowl practices at the end of the 2006 season, Boren had practiced exclusively at center.

Boren had been recruited as either a center or a guard, but he preferred to play guard.
In spring practice the following year, Boren was moved to center.
 At the end of the National Collegiate Athletic Association-sanctioned 15 days of spring football practice, he was announced as the starting center, replacing Mark Bihl.
 This decision was confirmed when training camp started in the fall, even though Boren had never before played center.
 Thus, the starting offensive line was composed of veterans Long and Adam Kraus on the left and then Boren, right guard Jeremy Ciulla and right tackle Stephen Schilling neither of whom had ever started a game.
The 2007 NCAA Division I FBS football season was eagerly anticipated for the 2007 Wolverines with returning seniors Long, Mike Hart and Chad Henne in key roles, but the season quickly began to fall apart when the team lost to the two-time defending FCS champion Appalachian State Mountaineers in the opening game.
When Ryan Mallett played in place of Henne during the September 15, Notre Dame rivalry game, left-handed snapper Boren switched positions with right-handed snapper Kraus who otherwise played left guard.
 The switch occurred after Mallett fumbled two snaps from Boren, whose left-handed snaps were foreign to the right-handed Mallett.
The switch caused a little confusion with official starting lineups the following week when Mallett started.
 On September 22 against Penn State, both Boren and Kraus had casts on their snapping hands and Boren played center despite the fact that Mallett was starting.
During Mallett's October 27 start in the Little Brown Jug game against Minnesota, Kraus started at center.
 The following week during the Paul Bunyan Trophy against Michigan State, the position switch was made permanent.
After the regular season, Boren was recognized as an honorable mention All-Big Ten selection.
Prior to the 2008 Capital One Bowl, Boren was expected to return to center because Henne had returned to full strength.
However, during the game, Boren played guard and Kraus played center.
 After the season, both Boren and Kraus were named to Jewish Sports Review's 2007 College Football All-America Team.

After the season, head coach Lloyd Carr was replaced by Rich Rodriguez.
 Rodriguez' no huddle spread option offense, which used zone blocking, was a major adjustment for Boren.
By the tenth day of spring practice Boren had left the team.
Boren made a statement to the press regarding his decision, which included the following excerpt: "Michigan football was a family, built on mutual respect and support for each other from (former) Coach (Lloyd) Carr on down.
We knew it took the entire family, a team effort,
