The first half of the Big 12 season is in the books. It’s been a strong first seven weeks for the conference, as four teams are ranked in the Associated Press poll and only one team is out of bowl contention (Kansas). The Big 12 still has a legitimate national title contender, along with two players who could get into the Heisman mix (Geno Smith and Collin Klein). It’s still a wide-open battle to win the conference, but Kansas State, West Virginia and Oklahoma appear to be the frontrunners. However, Texas Tech cannot be ignored after last week’s win over the Mountaineers.
