NIU ended that season 10-2 and defeated at least two ranked teams (at the time they played them). One of their losses was to #23 Bowling Green.
I’m not sure losing to them in 2003 is on par with NU 2017, but if it gives you hope...
Yep. In 2003 Huskies was somewhat powerful. Peak 2003 record. Unfortunately downfall ever since, like NU1994/95/97 vs. MR's years. In other words, absolutely no comparison with 2003-2017.
