In the off-season, several expansion teams were announced for the second season of MILA. The St. Louis Pride, Pittsburgh Octane, Southern Ohio Box Lacrosse, Cleveland Demons, Detroit Coney Dogs, and Nebraska Fighting Perkins were all announced before the end of the calendar year. Three more teams (Madison Capitals, Minnesota Jaxx, and Colorado Sabertooths) were also announced for the 2012 season. Nebraska never materialized and a group from Indiana took over the franchise rights, adding Indy Swagger to the league.

Colorado was crowned champion after the 2012 season, when 10 teams competed in league play. St. Louis and Nebraska/Indy failed to get its team off the ground.

Expansion was again on the off-season agenda as the Upstate Bears were named the 11th league member in February 2013. With the new geographical boundaries, the league again changed its name. In March 2013 MILA became the Continental Indoor Lacrosse League.

In May 2013, a league administration^[2] was announced. Grand Rapids GM Russ King was named commissioner of the CILL. Detroit GM Owen Blank (secretary) and Ray Kincaid (treasurer) of Chicago were also appointed.

Seven teams made up the CILL in 2013, with Colorado going undefeated to win the regular season and #1 seed for the CILL Cup playoffs. The Sabertooths went on to defeat Chicago 14-11 in the championship game and were crowned CILL Cup champions.
