I couldnt help but dig up some numbers. Take em how you want, I know what the results say.
These are based on 06,07,08 and 09 Regular seasons. No championship games included. it is a full cycle of schedules, every north team has played every south team both home and away.
there are a total of 24 seasons, 72 North vs south matchups, and 192 games per division
Now these are not biased to any individual team but to the divisions as whole, but followin will some individual team facts
The North teams have a combined conference record of 81-111 for a 42% win pct,
The South is 109-83 for 56%
North teams are 23-49 against the south for 31%
North teams have gone 3-0 agains the south part of their schedule just 2 times in the 24 seasons (Colorado in 07 and Kansas in 07)
North teams have gone 0-3 agains the south 9 times (6 of which by Kansas and Iowa St. 3 each)
2006- North was 5-14 against South
2007- 10-8
2008- 3-15
2009- 5-13
North teams have only 6 winning records against south teams in 24 seasons (Nebraska in 09, Missouri in 07, Kansas in 07, Kansas St. 06, 07, and Colorado in 07).
South teams have gone 3-0 against North teams 9 times in 24 seasons (2 times each by Texas, Oklahoma, Texas Tech, and Oklahoma St.) ***Baylor went 3-0 against the North in 06***
South teams went 0-3 just once (Baylor in 07)
North Has 17 winning seasons against North teams
No North team has a winning record against south teams in these 4 years, Kansas St. is 6-6 and Colorado is 5-7, Neb. and Miss. are each 4-8
Baylor has the worst record in the south against the north at 5-7, which is tied or better than 4 of the 6 north teams.
Oklahoma and texas and Oklahoma st are a combined 30-6 against the north. the 3 best North records are a combined 15-23.
LAST FACT, SOUTH HAS WON ALL 4 CCG'S
Now, i didnt feel like looking into the detail of figgerein out how many of the north wins came against Baylor and texas A&M, but Colorado did beat Oklahoma in 07, and Kansas St. is the only team to beat Texas from the North.
