In 2018, the Big Sky had 4 teams: Montana State 7-4, EWU 9-2, UC Davis 9-2, and Weber State 9-2 (left out: Idaho State and Montana had 6-5 records). In 2017, the Big Sky had 3 teams: Weber State 9-2, NAU, 7-4, and SUU 9-2 (left out: EWU and Sac St. had 7-4 records). In 2016, the Big Sky had 4 teams: Cal Poly 7-4, Weber State 7-4, UND 9-2, and EWU 10-1 (left out: SUU, Northern Colorado, and Montana had 6-5 records). Since UND is essentially a Big Sky school, in 2019 they will be behind these teams: Montana, Weber State, Sacramento State (DII win), and Montana State.
IMO The million dollar question is this: Is the Big Sky the strongest FCS league in 2019? If yes, the committee takes a 5th Big Sky team (either UND or EWU (DII win)) If no, both the Hawks and the Eagles are left out.
