Somebody else can talk about playoffs, but I want to talk about some tiebreaker scenarios. I'll do it in reverse alphabetical order.
Sun Belt: James Madison has clinched the East Division, but the West is open. If Southern Miss loses to Troy in 2 weeks, we could have a 3 way tie in that division with Arkansas St and each of them would be 1-1 against each other. This would give the division crown to Troy, because one of their conference losses is to Old Dominion, who is in the East Division. Of course, none of this matters is the Golden Eagles beat Troy (even USM losing their other remaining game wouldn't matter as they hold the tiebreaker over Arkansas St in a one-on-one scenario.)
SEC: There is no chaos scenario without a crapload of upsets. If Texas A&M beats Texas, they're in. If they lose, then the teams that get in by winning are (in order of who needs the least help): Alabama (beat Georgia), Georgia (beat Ole Miss, lost to Bama), A&M (played none of the above), then Ole Miss (0-1 against tied teams). The chaos scenario is if all of them lose. Then A&M is in (only one loss team) and we have at least 4 6-2 teams (Texas will have won their game against A&M plus probably Oklahoma and possibly Vanderbilt.)
Mountain West: They're already in a chaos scenario. San Diego St is 5-1 and a whopping 5 teams are 4-2... and only two of them have a game against each other remaining... and another plays San Diego St, which can make this even more difficult. I'll keep an eye on this conference.
MAC: Very similar to the Mountain West, there's one 5-1 team and 5 4-2 teams. The two differences are that there are two games between 4-2 teams and they have too many teams in this conference for them all to have played each other. This one will likely mostly sort itself out over the next two weeks (probably starting on Tuesday).
Conference USA: This is not as bad as it seems. Even though there are three teams tied for second place, one of them is Missouri St, who is ineligible to play in the conference championship. The undefeated team, Jacksonville St, has clinched their spot in the game, but their opponent and home field advantage, are still to be determined. Western Kentucky can host the game by beating Jax St in two weeks or get a rematch in the championship game if Kennesaw St loses one of their remaining games.
Big 10: It looks like Ohio St and Indiana will meet in Indianapolis, but with two one loss teams (currently three, but two play against each other), you can't take your eye off of this race until two of them cross the finish line. Either USC or Oregon will be knocked out of contention this week and 6-1 Michigan finishes the season against 7-0 Ohio St, who they have beaten each of the last four years.
Big 12: A rematch between Texas Tech and BYU seems likely, but Cincinnati is 5-2 and plays the Cougars. Houston, Arizona St, and Utah are also 5-2 and just waiting for one of those teams to fall off their perch in what would possibly be the example for why there are so many levels of tiebreakers for years to come.
ACC: Four teams have one loss in this conference and only two of them (Pittsburgh and Georgia Tech) will play each other. None of these four have played against each other so far this year, so the tiebreakers could go pretty deep.
AAC: None of the one loss teams have a game against other this week or next, but because some of them have played already, the hierarchy is pretty easy to see: North Texas and Tulane hold victories over Navy and East Carolina, which puts them in control. Navy and East Carolina need the right one (or both) of them to lose and they need to win out. Keep in mind that Navy has only one relevant game as the Army-Navy Game is after the conference championship and does not impact the standings.
