In the 2011-12 season, however, Cooper, Braden, and the Blue Jays came out just as strong. They recorded a 14-2 SLIAC record to once again win the regular season, and won the SLIAC Tournament for the first time, receiving the program's first-ever NCAA Tournament bid.

The 15-16 season yielded yet another SLIAC regular season winner, with a team that went 16-2 during the regular season. After losing in the championship of the SLIAC Tournament, the Blue Jays had yet another 20-win season with a record of 21-5. 

In 2017-18 the Blue Jays recorded the top three records for points in a game in school history, while improving the win total from the 2016-17 season. The squad reached the SLIAC Tournament title game for the fourth time in school history, becoming the first-ever No. 4 seed in the tournament to upset the top seed and advance to the championship. The team was ranked No. 2 nationally in offensive rebounding.  The Blue Jays also ranked No. 17 in the nation on WBCA Academic Honor Roll.
