the rankings are so biased and subjective,,too much beauty contest and where teams start teh season ranked involved...

If you did the same analysis on wins vs teams with three or fewer losses and or used FEI and S#P8 statistical rankings instead of the other polls..the data would start to make more sense and paint a clearer picture...i think...

FEI is found at footballoutsiders.com

Anyway. I love analysis like you did, but unfortunately as i said the polls ap and coaches are TERRIBLE measurements and don't represent True rankings of teams except of those voters opinions instead of rankings backed by data.

Which is why i think using a three loss or less metric or the rankings I suggest will supply more meaningful data..
