Things to watch in Week 6 in the Big 12, when all four of the league's undefeated teams are playing away from home:
GAME OF THE WEEK: No. 2 TCU (5-0, 2-0 Big 12) at Kansas State (3-1, 0-1). While the Wildcats are quickly going through quarterbacks, TCU plays the second of three Big 12 road games in a four-week span that coach Gary Patterson calls the most important stretch of the season. The Horned Frogs finally get an open date after K-State and then a trip to Iowa State. After Oklahoma State's final-minute field goal to beat K-State 36-34 last week, coach Bill Snyder's team probably can't afford another loss and still have any realistic chance in the Big 12 race.
