re: Has a region of the country ever dominated CFB for this long?

The southeast portion of the country has dominated college football for decades For awhile it was:
Florida
Florida State
Miami
Tennessee

Then Alabama
Auburn
LSU
Florida
Clemson

Now it is
Alabama
Georgia
Clemson
LSU

There have been a time or two in that time frame that Ohio State or Texas won a Championship. VBut it's been awhile since one section of a country has been more dominant than the Southeast United States.

(Before people jump on me, I'm sure I may have forgotten somebody. no slight was meant.
I don't see it ending any time soon.
