This year I have:
I definitely agree with you that these 4 teams should be in the 2017 college football playoff.
I also agree with your order from 1 through 4.
Especially after Auburn got their 3rd loss today.
Also, the one loss Wisconsin received today eliminates them because of their weaker schedule.
The one thing I disagree with you on, is their being a big gap between Georgia and Alabama.
I believe all 4 teams are close to being equal.
I believe anyone of these four teams is good enough to win the national championship.
