Its not only who the top B12 teams have played but how they have won. There have been quite a few ugly games SEC teams have won or lost that if they were as good as they thought wouldn't have been close.
OKlahoma has nearly scored 50+ on everyone and they have two quality wins against 4-1 Big East contender Cincinnati and 4-1 MWC contender TCU.
Texas has blown out SEC Arkansas and Colorado on the road. They have also scored nearly 50 points a game and have dominated every team they played. Btw 5 of their next 6 games are against top 20 teams.
Missouri beat Illinois in its first game, blew out Nebraska for its fist win in Lincoln is about 30 years. They have also never really had a close game except IL who scored a ton towards the end of the game.
Texas Tech hasnt really played any great teams but also the games have not been close. They have blown everyone out by 30 points except when they played @ Nevada and the won that one by 16.
Unlike the SEC teams, the B12 teams have beaten everyone they were supposed to. Their offense are 10X more explosive than any SEC offense. Florida is basically Tebow and Harvin, UGA got exposed by a very good Bama team.
The SEC has better defenses but I would wager OU, Missouri, Texas Tech, and maybe even Kansas would score at minimum 30 points on any SEC D.
Now lets look at the SEC unbeatens
LSU 4-0 - App State, North Texas, @ Auburn , Miss State I guess you could say Auburn is their toughest game, Auburn sucks and mightly LSU won by 5.
Vanderbilt 5-0 - Miami (OH), South Carolina, Rice, Ole Miss, @ Auburn They certainly should be ranked but they played two cup cakes and 3 bottom half SEC teams.
Bama 5-0 - The only SEC team with Resume especially in the OCC. They blew out Clemson, but they also got beat by Maryland so yeah. The exposed UGA and could have beaten them 62-0 if they didnt pull the reigns back in the second half.
Imo Florida, Georgia, Auburn, and Tennesee are all WAY over hyped comming into the year and their results have proven that. Tebow cant win a game if they trail in the 2nd half, he is superman but pressure is his cryptonite. Auburn has maybe the worst offense of any BCS team in any conference. UGA has a great RB, a senior QB who has never taken the next step, and a coach that always seems to lose a big game. UT just plain sucks, 3 BCS teams played and 0-3 in those games.
I think Vandy will come back to earth, they are not as good as LSU, Bama, or even UF or UGA imo.
Alabama if they can avoid the fall like last year has proven to be the class of the league. LSU may well be better but needs to play a team with a pulse to prove it.
