Also lets look at other probable bubble teams:
6-4 Western Illinois hosts 3-7 Southern Illinois
6-4 Cal Poly hosts 6-4 Northern Colorado
7-3 Wofford hosts 3-7 VMI
6-4 New Hampshire hosts 6-4 Maine
7-4 UT Martin goes to 9-1 J'Ville state
5-5 Northern Iowa hosts 7-3 South Dakota State
6-4 Weber State hosts 2-7 Idaho State
7-3 Samford goes to 4-6 ETSU
You've also got some matchpus for auto-bids in the conference that could help or hurt bubble teams.
8-2 NC Central hosts 9-1 NC A&T (winner gets conference bid I think) An NC Central win probably pushes a bubble team, an A&T win probably helps bubble teams. A&T is 9th in the FCS while NC Central is 24th. I assume an NC Central loss would knock them off the bubble, too weak of a conference. However an NC Central win probably puts both them and A&T in the playoffs.
8-2 Lehigh travels to 2-8 Lafayette. Lehigh has won the Patriot, a win or loss doesn't matter, they beat Fordham their only other possible contender for the conference and hold the tie breaker over them if they lose.

Best case for the Griz
1. A big convincing win against Montana State.
2. UT-Martin loses to J'Ville (J'ville is favored)
3. NC Central loses to NC A&T (NC A&T is favored)
***Honestly I think if those three things happen, the Grizzlies chances to keep playing football beyond Saturday are pretty good.***
Then there's UNI. A UNI win would be a help for Montana more than a hindrance. If UNI wins they're 6-5 and a bubble team. But presumably if UNI gets in, Montana gets in. As the Griz would be 7-4 and had beat UNI in their own house. There's the slight outside argument that UNI as a bubble team and playing better football down the stretch would hop over Montana though. So a UNI loss isn't that devastating for UM either, as they'd have one less bubble team to contend with
Beyond that with the other match-ups a surprise upset loss by Wofford, Western Illinois, or Samford would be a boost.
Cal Poly and UNC will result in one team being 7-4 and the other being 6-5 so one could be in while the other would be out. If UNC wins they'll only have 6 D1 wins, where if Poly wins they'd have 7. I think a Poly win would be more beneficial as they have the better resume overall.
New Hampshire vs Maine are two bubble teams as it is. Just like the Poly vs UNC game one will still have a shot while the other will be out. A quick looks suggests Maine's SoS is better than UNH's.
Weber could play a role in this too, assuming they win they're also 7-4 and would have beat Cal Poly, who beat us. A Weber loss helps the Griz big time, but I don't see that happening against Idaho State. It is in ISU... so who knows.
