Week 3 is upon us in the Big 12. And if you believe in the power of momentum, the league appears to be in store for more trouble. On Saturday, Oklahoma State and TCU got tangled in one-score battles in the final minute. Both nationally-ranked Big 12 programs appeared to be in position to win in the closing seconds, yet both lost -- TCU in double overtime to Arkansas after Ryan Graf's 28-yard field-goal attempt was blocked with 16 seconds to play in regulation, and Oklahoma State to Central Michigan on the most bizarre finishing sequence of the young season.
