I've seen projections at this point with anywhere from 3-4 Big Sky teams making the field. Who those teams are varies... I think if the Griz win out, getting to 8-3 they WOULD BE IN. They would have won 6 out of their last 7 and beat the #9 team in the Country (committee playoff rank at the time) with their 4th string QB at home. Eastern wouldn't be a bad loss, at the time Eastern was #11 in the Country and the game was close. The Griz had a big time rally against Weber State and just ran out of time. So the Griz would be coming in to the playoffs winning 6 out of their last 7 with a signature win. Griz will not make it at 7-4 this year, but would have last year.

A UC-Davis win this weekend would really help the Grizzlies case. If the Jacks of Northern Arizona and UM both finish 8-3 with identical conference records, i'm not sure how you would argue NAU should make the playoffs ahead of the Grizzlies if you are using the same logic that Haley is using to pick Eastern over the Griz. I'm not so sure a 7-4 Eastern team would get in over an 8-3 Griz team. Weber State is basically a lock at this point. I think the Big Sky definitely gets 3 teams in, likely 4. So that would leave Montana, NAU and Eastern and Southern Utah for the final 2-3 spots. Montana would be coming in the hottest potentially. If Southern Utah was to lose to NAU in the final game of the season, that would be interesting. I could see 4 Big Sky teams getting in, but it also would depend on what happens in the other conferences. My belief is an 8-3 Griz team would stack up favorably when selecting the 24 teams for the FCS playoffs.
