I was doing a semi-countdown in the realignment thread, so I'll just move it over here.
Last week
SEC: Alabama took care of business with Tennessee and Georgia had the weekend off. These are the only two realistic possibilities.
big 10: Penn State dropped one they shouldn't have, and is now likely all out of the hunt. Michigan, Michigan St, and Ohio State all still control their own destiny. Iowa still technically in it, but will need help.
Pac: ...
Big XII: Gundy gonna Gundy. BlowU is the only realistic possibility now. Okie Light and Baylor still technically in it, but will need help to climb back into the conversation.
Coastal lost their mid-week game too, so the only other teams left are ND and Wake Forest (who hung 70 on Army btw). Oregon is still technically there, but isn't doing anything to impress the committee and could easily be jumped by ND and WF in the rankings before their CCG, if they make it that far.
So, things continue to look better and better for future conference member Cincinnati.
SEC: With Kentucky and Ole Miss losing, this now leaves Alabama and Georgia as the only mathematically possible teams to make the playoffs from the SEC.
big 10: Iowa continuing to be Iowa and is now eliminated entirely. Michigan is out as well. Only Ohio State and Michigan State stand a chance at making it, and they still have to play each other. Loser is eliminated from the title hunt.
Pac: I know I keep leaving Oregon out of this, even though they're still technically in the hunt. But realistically, they're going to get leap frogged by teams behind them in the rankings before they're likely to hop in themselves.
Big XII: BlowU is it. Baylor and OSU still there, but like Oregon and Ohio State, they'd need help to make it into the conversation.
ACC: Wake Forest still making waves, still undefeated. I'm afraid they won't be able to control their own destiny though due to the brand on their helmets. Big test for them this weekend though going up against North Carolina
The rest: ND beat NC to at least stay alive, but will needs some teams ahead of them to lose.
Things continue to look good for Cincinnati. Thanks to some other teams losing games they shouldn't have, Cincy just about controls their own destiny at this point. If they win out, the only scenario that they really have to worry about is Michigan State going undefeated, Oklahoma going undefeated, and Alabama upsetting an undefeated Georgia in the SEC championship game. I don't think even an undefeated Wake Forest is enough to drop them out of the top 4.
Lots of football left to be played though.
