Week 7 Thoughts:
-Within a bit into the season, the top 6 for the national championship seemed to be Alabama, Georgia, LSU, Ohio State, Oklahoma, and Clemson. We can add a couple other to that list now, but we finally had our first loss from that group with Georgia surprisingly losing at home to South Carolina.

-The SEC East in general had a tough week at the top with Florida losing too. Both Florida and Georgia do still control their own destiny for a national championship, but no longer have any margin for error. Winning out the rest and losing the SEC Championship likely won't be enough.

-Oklahoma winning the Red River Shootout was a big deal. It keeps only them and Baylor alive for a CFP bowl.

-The MAC is the first conference to be permanently deleted from the 1-loss category.

-For the Group of 5 bid, we had a few important things. Memphis had their first loss in a game at Temple. This leaves just SMU undefeated in the American (although there five 1-loss teams). In important games, both Boise State (vs. Hawaii) and Appalachian State (vs. Louisiana-Lafayette) won. San Diego State meanwhile won the battle of 1-loss teams vs. Wyoming in the Mountain West. It will reveal a lot when the committee comes out with rankings. Several questions here like: 1. Who will be higher if both are still undefeated SMU or Boise State? 2. If still undefeated, how does Appalachian State compare to the 1-loss teams in the American and Mountain West? 3. How will the committee view the top 1-loss team in the American?

Week 8 Thoughts:
We have no games between undefeated teams this week. Our undefeateds play in the followings games: undefeated Ohio State @ Northwestern (Friday), undefeated LSU @ Mississippi State, undefeated Minnesota @ Rutgers, undefeated Clemson @ Louisville, West Virginia @ undefeated Oklahoma, undefeated Wisconsin @ Illinois, 1-loss Temple @ undefeated SMU, Louisiana-Monroe @ undefeated Appalachian State, undefeated Baylor @ Oklahoma State, 1-loss Michigan @ undefeated Penn State, Tennessee @ undefeated Alabama, and undefeated Boise State @ BYU.

Our winless teams are in the following games: Buffalo at winless Akron and winless Rice @ UTSA. New Mexico State is off.

1-loss Michigan @ undefeated Penn State: Both teams just beat Iowa by fairly similar margins (although Michigan was at home and Penn State away). Win this and the narrative around Michigan this year starts to change. If Penn State wins, it leaves them and Ohio State the two dominant teams in the division at this point and Penn State will have the better wins so far (Ohio State's biggest games so far look like less than they did at the time).

Undefeated Clemson @ Louisville: Louisville will be a huge underdog, but did just defeated the only other undefeated ACC team in Wake Forest.

1-loss Temple @ Undefeated SMU: Temple just beat the next to last undefeated from the American in the form of Memphis. Win this and Temple will be a very legitimate NY6 contender. On the SMU side, they might control their destiny (depending on if committee likes them or Boise State better). Lose this and they won't.

Undefeated Baylor @ Oklahoma State: Bears might be underdogs here this week, but they keep winning.
Undefeated Boise State @ BYU: Doubt BYU could pull this off, but at their best they did beat USC this year.

1-loss Oregon @ Washington: Oregon is the PAC-12's best hope. With 2 losses Washington is likely out of CFP bowl race, but very much in the PAC-12 championship/Rose Bowl race. Winner here will be favored to win division.

1-loss Arizona State @ 1-loss Utah: Winner of this will be the only possible remaining 1-loss team in conference after this week beside Oregon. While a long, long way to go, they would be only other small hope for a CFP bowl spot. Otherwise could still be big for division at least.

1-loss Tulane @ 1-loss Memphis: Two of the 1-loss teams in the American. Can Memphis recover from last week?

Remaining Undefeated Teams: ACC: 1, American Athletic: 1, Big 12: 2, Big Ten: 4, Mountain West: 1, SEC: 2, Sun Belt: 1, total: 12

Last week there were one guaranteed (UF@LSU) and 11 additional possible games between undefeated teams.  Now there are a lot less due to the four losses among undefeated teams this week (UF, UGA, Wake, Memphis).  The remaining potential games between undefeated teams outside of the playoff are:

• 10/26:  Wisconsin at Ohio State
• 11/9:  LSU at Bama
• 11/9:  Penn State at Minnesota
• 11/16:  Oklahoma at Baylor
• 11/23:  Penn State at Ohio State (if this happens it will be for the B1G-E slot in the B1GCG)
• 11/30:  Wisconsin at Minnesota (if this happens it will be for the outright B1G-W Championship)
• B1GCG*

*B1GCG:  This can only match undefeated teams if it is:

• tOSU vs MN or 
• PSU vs UW

There are seven theoretically possible games between undefeated teams but only a maximum of six could possibly happen because the result of #3 (PSU @ MN) will eliminate either #5 (PSU @ tOSU) or #6 (UW @ MN).  Even six is, obviously, unlikely in the extreme.  

Undefeated teams in the polls (using AP here):

• #1 Bama
• #2 LSU
• #3 Clemson
• #4 Ohio State
• #5 Oklahoma
• #6 Wisconsin
• #7 Penn State
• #14 Boise State
• #18 Baylor
• #19 SMU
• #20 Minnesota
• #24 Appalachian State

This is the first week this year in which all of the undefeated teams are ranked.  

The contiguous block of undefeated P5 teams at the top shrunk this week to seven.  UF and UGA dropped out of that group while Penn State jumped in.  The only remaining undefeated P5 teams NOT in that block are #18 Baylor and #20 Minnesota.  

Playoff chase:
At this point it is safe to say that all of the undefeated P5 teams control their own destiny.  Even #18 Baylor and #20 Minnesota would easily jump WAY up to the top-4 if they won out because winning out would include multiple impressive wins.  

The B1G (4), SEC (2), B12 (2), and ACC (1) each have at least one undefeated team and so long as that remains the case, those teams are your CFP teams.  It is, however, extremely unlikely that those four leagues will each produce undefeated champions and that is where it will get interesting.  

My best guess right now is that after the four potential P5 undefeated teams the next highest potential CFP teams would be:

• A 1-loss SEC Champion
• A 1-loss B1G Champion
• A 1-loss Clemson
• A 1-loss Oklahoma
• A 1-loss Notre Dame
• A 1-loss Pac Champion
