In 1997, there was a change in the administration of NCSA Region III. Eric Sztul, who at the time was a member, and coach of the Bowling Green Men's Club Soccer Team, took over the leadership of the conference. In that season two more teams were added, Indiana and Toledo. The league was becoming more well known and resepected throughout the country, especially when Michigan won the NCSA National Championship.
In 1998, expansion was again occuring in the conference, adding Miami and Purdue. The competition and overall organization was also growing in the league, with as many as five teams going into national, post-season play. Once again, Michigan won the NCSA National Tournament.
1999 became a defining year for the conference. With the NCSA falling apart, and later dismantling, the conference had no identity, and no association with a governing body. As a whole, the league decided to join NIRSA (National Intramural and Recreational Sports Association). Joining NIRSA was the best decision for the conference. NIRSA provided weekly rankings and stable ground for a growing soccer league. The conference officially became known as the Midwest Alliance Soccer Conference, and added three new teams, bringing the total to fourteen. The new teams were Central Michigan, Ohio University and Western Michigan. The conference also sent three teams to the NIRSA National Championship that year.
Entering the new millenium, the MASC had a brand new look. Membership had risen to eighteen teams, with the additions of Grand Valley State, Northern Illinois, Xavier and Dayton. The league divided its competitors into two divisions, the East and West, which created some new rivilaries. The conference sent three teams to the NIRSA National Tournament.
In 2001, the MASC had grown to 21 teams with the additions of former member Ball State, Eastern Michigan, Ferris State and Wright State. The league had expanded to three divisions and its teams
continued to enjoy success at the National Tournament.
The MASC grew again for the 2002 season adding four new teams and bringing the total to 25 teams. Cincinnati, Michigan State, Southern Illinois and Western Illinois began play and league newcomer, Wright State, won their second consecutive tournament championship.
In 2003 there was a change of administration. Richard Becknell, former coach and advisor for the Ohio University Club team took the reigns of the league. Eric Sztul took over the Assistant Commissioner title.. With Becknell's insight, dedication, and passion for club soccer, the league continued to strive to be the best club soccer league in the country.
Since 2004, several new clubs have entered the conference, including Loyola-Chicago, Butler and Indiana University-South Bend. In 2005, an entire new division was added, the Great Lakes Division,
which includes clubs from both the Upper Peninsula of Michigan and the state of Wisconsin. This new addition brings the MASC into full geographic representation of NIRSA's Region III institutions, as well as marking the largest single expansion in league history. With the additions, the MASC became the largest soccer conference in America.
The 2006 season was an unprecendented season as four member teams made the National Quarterfinals. In the National Championship, Michigan defeated Illinois in an epic battle.
Indiana University won the 2008 National Championship, thus continuing the long history of dominace for NIRSA Region III clubs. Indiana's National Championship recorded the fifth National Championship for the MASC in the past 11 seasons.
At the beginning of the 2009 season, the league has 39 league members, along with six associate member clubs. The MASC is one of the strongest Club Soccer Conferences in the country, and continues to strive to be the best.
